thinking about sudden and surprise new parent reader fumbling at the little grocery store that has lights that are quiet enough, cart full of everything you think you might need but still you don't head for the register because what if you're missing something really important? and you don't have anyone you can call so you're left with a sweet sleeping infant and an arm that's screaming from having to hold her up and sweat pooling on your temples and the bittersweet scent of the desperate need for a pack that alex picks up the moment he steps through the automated doors. he quickly tracks you down, concern brimming, because you've never smelled like that before, you've always been friendly and chatted so sweetly when your carts have crossed paths and he always finds himself looking forward to bumping into you so what if this sudden change means it's because you're hurt? but when he spots you, smiling down at the little girl in your arms even as your eyes shine from unshed tears, he knows. he's yours, he was always meant to be, always belonged to you and that darling girl with a head full of dark hair

ive been obsessed with wolfheart for months, ty for feeding us the good food

I'm more than happy to provide <3 (Seriously I am so happy Shadowheart is a furry, werewolves activate the neuron for me).

[marlynnofmany]

Hey, let's overthink werewolves some more. Why does the full moon make them change, anyway? Do they have to get Maximum Moonlight, and any other night isn't enough? What about when the moon is full during the day, when it's just not as noticeable? What's so special about the moon, which is just reflecting light from the sun? While we're at it, stars are just suns that are far away.

Sounds like their particular brand of magic is a delicate balancing act of how much solar radiation they get at a given moment. And possibly there's something about lunar dust that kicks it into high gear.

Questions:

*Do the moon rocks that the astronauts brought back do anything?

*What if an astronaut was a werewolf?

*Since werewolves change even when they're indoors, then the relevant bits of moonlight can pass through such things. Are there any scientists around who can tell us whether there's a wavelength of light that could bounce off the moon but not off a door?

I mean, the alternative is "because the magic says so," and that's just the easy way out.

Book recs: Queer horror, part 1

We all like a good horror story, right? You know what's even better? A queer horror story!

A note: queer here does not necessarily mean “guarantee of an f/f or m/m ship with a happy ending”, but rather simply a significant presence of queerness. Some of the books feature no romance but has a same gender attracted/trans/ace spectrum lead, or features an m/f relationship with bisexual, trans or aro/ace characters, or simply features a world-building which is heavily queer inclusive in ways that don’t always compare to our own ideas of sexuality and gender. I have however disqualified works where the only queer presence is along the lines of “gay best friend” or a blink and you’ll miss it confirmation that never comes up again.

For more details on the books, continue under the readmore. Titles marked with * are my personal favorites. And as always, feel free to share your own recs in the notes!

Camp Damascus by Chuck Tingle*

Rose, like her parents, believes strongly that homosexuality is a sin, and holds great pride that her home town hosts Camp Damascus, a successful conversion camp for young teens. But Rose is also experiencing strange and terrifying things: memories of a beautiful girl, a demonic figure that shows up if her thoughts stray, flies crawling out her mouth. Something has happened in Rose's past that her parents won't speak of and that she herself can't remember, and Camp Damascus is at the center of it all. Sapphic, autistic main character, as well as a really cool take on demonic lore that is both inspired by and a subversion of christianity.

House of Hollow by Krystal Sutherland*

Young adult. Something happened to Iris Hollow and her two older sisters when they were little; after having gone missing, they were all returned with no memory of what happened and identical scars on their throats. Years have passed since then, and though seen as strange the girls still lead mostly normal lives - that is, until the oldest, Grey, goes missing, leaving strange clues in her path. As Iris searches for her, a strange man with horns starts stalking her and memories start to rise to the forefront in her mind. To save Grey, Iris will have to find out the truth of what happened all those years ago. Features wonderfully morally grey characters. Bisexual lead, but little to no romance.

Winter Tide (The Innsmouth Legacy) by Ruthanna Emrys*

Aphra and her brother are the only survivors after the government raided their home, Innsmouth. Their only living family are the amphibian people of the deep, whom they will one day join, but until then they are bound to land where they struggle to build new lives for themselves after the great loss of their home and loved ones. Then rumors start to spread of a russian agent seeking dangerous and ancient magic, forcing Aphra to involve herself as they try to stop it. Does contain horror elements but is generally a much more optimistic look on cosmic horror than most lovecraftian stories, told from the perspective of one of his monsters. Lots of focus on found family and rebuilding of community. Asexual main character (however I don’t think that becomes in-text confirmed until the sequel) and multiple queer characters in the supporting cast.

Rules for Vanishing by Kate Alice Marshall

Young adult. One year ago, Sara's sister went missing. Since then, Sara has drifted away from her friends, but when she receives a mysterious text inviting her to "play the game" - the same game that supposedly stole her sister away - Sara and her estranged friends all come back together to find her. Together they set off on a path that legend says appears only once a year, leading them toward the ghost Lucy Gallows and, hopefully, Sara's sister. Bisexual main character, told in a faux documentary style.

Sorrowland by Rivers Solomon

A young pregnant woman flees a cult that left her body strange and changing in terrifying ways. Hiding from both a world wanting to oppress her and the cult seeking to force her back, she does her best to raise her children while trying to find out the truth of the cult and being pursued by a hunter in a dangerous game of cat and mouse. Bleak and scary, Sorrowland is a book that will creep under your skin with horrors both fantastical and very, very real.

Otherside Picnic (Otherside Picninc lightnovel series) by Iori Miyazawa

Sapphic light novel with a surreal and episodic horror vibe. Following the directions of an urban legend, university student Sorawo finds her way to a reality populated by horrifying creatures from ghost stories and modern urban legends (of which I’m sure you’ll recognize many). Here she teams up with fellow explorer Toriko, both to find out more about this strange world and to help Toriko find a missing loved one. Also available as a manga and (one season of) an anime. Sapphic.

Our Wives Under the Sea by Julia Amrfield

Miri thought she lost her wife Leah when her deep-sea mission ended in a catastrophe. But Leah was miraculously returned to her - or so it seems. Because something happened down there, deep in the ocean, and whatever it was, Leah has brought it back with her. Surreal and strange, Our Wives Under the Sea will not answer all your questions, but it will give you a unique experience.

What Moves the Dead by T. Kingfisher

Novella. Alex Easton, retired soldier, travels to visit their childhood friends, siblings Madeline and Roderick Usher, after finding out that Madeline is dying. In the siblings’ rural, ancestral home, Madeline walks in her sleep and looks to be fading away, while around it wildlife seems to be possessed by a strange force. With the help of a mycologist and an American doctor, Alex attempts to save Madeline and reveal the truth of her illness. Nonbinary main character.

Alien: Echo by Mira Grant

Young adult. Twin sisters Olivia and Viola’s parents are both xenobiologists, bringing them all over the galaxy. Most recently they’ve settled on a new colony world to study its wildlife, but it proves more dangerous than they could’ve ever imagined. Under attack from alien monsters, the sisters must keep each other alive while also coming to terms with a dark family secret. Sapphic horror. Part of the Alien franchise but stands well on its own.

Into the Drowning Deep by Mira Grant*

A research vessel heads towards the Mariana Trench in search of answers of what happened to a ship which mysteriously lost all its crew some time earlier. In the deep dark, something intelligent and hungry awaits them. Very much mermaids of the horror variety. Sequel to a novella, can be read as a standalone. Also contains a sapphic romance, however that is a pretty small part of the plot as a whole.

Alice Isn't Dead by Joseph Fink

Based on the podcast by the same name. Keisha Taylor thought she had lost her wife. She even held a funeral and attempted to move on with her life. But then Alice started to appear, all over America, in the background of every single major tragedy in the country. To find her missing wife, Keisha gets a job as a trucker and sets out on a roadtrip, not knowing what horrors awaits her.

Wilder Girls by Rory Power

Young adult. Over a year ago, the Raxter School for Girls was hit by the Tox, a strange disease that killed off many and left the survivors’ bodies slowly changing in terrifying ways. The island the school is on has been in quarantine since then, and the girls dare not leave the school grounds lest they become victims of wild animals changed by the Tox. But as they wait for the promised cure, one of the girls goes missing, and her friends are willing to do anything to find her. Unsettling, spooky, and sapphic, this is a unique read featuring body horror and messy, dangerous girls.

Meddling Kids by Edgar Cantero

Once, Andy, Kerri, Nate, Peter and their faithful dog were known as the Blyton Summer Detective Club, until they hit their fateful final case in 1977. Now, the year is 1990, and the group hasn't gathered in years. Tomboy Andy is wanted in at least two states; Kerri, former kid genius, is tending bar; and horror nerd Nate is in a mental institution in Arkham. At least he still has the company of jock-turned-movie star Peter - except Peter has been dead for years. Now they must all come together to find out the truth of what happened all those years ago. Lovecraftian horror with a sometimes absurdist vibe and adult scooby do inspiration. Sapphic romance.

Contagion by Erin Bowman*

Young adult. After receiving an SOS, a small crew is sent on a standard search-and-rescue mission. But what they find are not survivors awaiting help, but an abandoned site, full of dead bodies and crawling with something… monstrous. No romance, but features one sapphic co-lead and one who can easily be read as demisexual (however this doesn’t show up until book two, which has more romance).

Sawkill Girls by Claire Legrand*

Young adult. The isolated island of Sawkill Rock has secrets. It hosts the legend of a local monster, and the very stark reality of decades of girls going missing, never to be found again. Now, three girls stand at the center of the horrific mystery - if only they can come together, perhaps they can save future generations of girls from a monster that may very well be real. Asexual and sapphic main characters, including a sapphic romance.

Salvation Day by Kali Wallace

A decade ago, the massive ship House of Wisdom was abandoned in orbit after its entire crew was killed in an outbreak in a matter of hours. Now, Zahra and her family of outcasts hope to claim the ship as their own by kidnapping the sole survivor to gain access. But the danger of the House of Wisdom is far from gone. Horror, no major romance but one of the main characters is gay.

The Luminous Dead by Caitlin Starling*

Possibly one of the most unstintingly claustrophobic books I’ve ever read, and definitely the most claustrophobic. Gyre, a caver on an alien planet, ventures into the dark and dangerous underground, guided only by a woman who has no compunctions on using and manipulating Gyre as she sees fit to obtain her secretive goals down in the caves. Sapphic in the most messy of ways.

Gideon the Ninth (The Locked Tomb series) by Tamsyn Muir*

Gideon, raised as a swordswoman by unfriendly nuns, would rather run away and make her own life, but her services are needed. The Reverend Daughter, Gideon’s childhood nemesis, has been invited to a trial to win a place as an immortal by the Emperor’s side, and she’s in need of a bodyguard. Listen, if you’re on tumblr I probably don’t need to explain this book to you. Trust me when I say it’s exactly as good as people claim. Humorous and spooky but also absolutely gut wrenching and clever with a lot of political commentary. There are also, indeed, lesbian necromancers in space.

Family Business by Jonathan Sims

By the author behind the Magnus Archives. When Diya's childhood best friend and roommate unexpectedly passes away, Diya falls apart and, among other things, loses her job. When she's offered a position at Slough & Sons to clean up after the deceased, she sees no other recourse but to accept. Her new job is grisly but important, and Diya starts to get back on her feet - until strange visions of a terrifying man and the dead's last moments start to haunt her. Slough & Sons are hiding something, and it's up to Diya to find out the truth. No romance, bisexual main character and trans woman side character.

Sodom Road Exit by Amber Dawn

Starla didn't want to return to her childhood home of Crystal Beach, Canada, but growing debt has forced her to move back in with her mother, despite the trauma hidden in her old home. But Starla is haunted by more than trauma; she is, in fact, literally haunted, by a ghost that may understand her, but may also consume her. Not overly scary, but handles dark subjects such as childhood sexual assault. Lesbian main character and romance.

House of Hunger by Alexis Henderson*

In a world where the rich drink blood to preserve their health, Marion applies to a position as bloodmaid in a notorious noble house far from home. Suddenly showered with luxuries and debauchery, Marion soon gains the interest and favor of Lisavet, countess of the house. A fresh take on the idea of vampires and deliciously dark sapphic romance inspired by the horrific real-life Elisabet Báthory.

A Dowry of Blood by S.T. Gibson

Dracula inspired novella, following Constanta, who’s turned from a medieval peasant to an undead bride. As time passes the relationship between Dracula and Constanta grows all the more strained and potentially dangerous. Teaming up with his two other consorts, she seeks to unravel her husband’s secrets. Sapphic and polyamorous.

Dread Nation (Dread Nation duology) by Justina Ireland

Young adult, alternate history. In this world, the war between the American states is interrupted when the dead start walking the earth and hunting the living. Jane McKeene has been trained at Miss Preston’s School of Combat to become an attendant, skilled in combat as well as etiquette to protect the wealthy. But Jane wants a different life, and in her search for it stumbles headfirst into a conspiracy. Bisexual main character, aroace side character (who becomes a POV character in the sequel).

Manhunt by Gretchen Felker-Martin

In a future where those with high testosterone are afflicted by a zombie-like disease, bloodthirsty men have become the enemy. Trans women Beth and Fran and trans man Robbie do their best to survive in this brutal world, where TERF movements seek to exterminate them and monstrous men hunt in the wilds. VERY gruesome and bleak, but also very timely in the present political climate.

Leech by Hiron Ennes*

Unbeknownst to humanity, a sentient hive mind has taken over the entire medical profession to ensure the health of their host species. One of their doctors is sent off to an isolated location where they’re cut off from the rest of the hive mind, only to realize they’re faced with a rivaling parasitic entity. Leech hands you only just enough information to get by, and whether its historical fantasy, an alternate timeline, or futuristic post apocalypse is hard to determine. It’s spooky and a bit weird and wildly creative, and does some neat things with gender.

The Outside by Ada Hoffman*

AKA the book the put me in an existential crisis. Souls are real, and they are used to feed AI gods in this lovecraftian inspired sci-fi where reality is warped and artificial gods stand against real, unfathomable ones. Autistic scientist Yasira is accused of heresy and, to save her eternal soul, is recruited by cybernetic ‘angels’ to help hunt down her own former mentor, who is threatening to tear reality itself apart. Sapphic main character.

The Gilded Abyss by Rebecca Thorne

Nix Marr is a soldier and damned good at it, but that doesn’t prepare her for her next mission: bodyguard for Subarch Kessandra, beloved royal and Nix’s bitter ex. The two venture toward the underwater city of Fall to seek the cause of a bloody murder spree and a possible deadly contagion. But Kessandra has enemies, the answers she seeks marking her as a possible threat for the nation’s rulers. On their way in an isolated and enclosed underwater ship toward Fall, the contagion catches up, and Nix will have to put her hurt feelings aside if the two are to arrive alive. Sci-fi with flavors of horror and the supernatural and a sapphic romance.

can vamp Tim give Jason a blood transfusion if needed? 🤔

in your vamp/wer verse I mean

Oh, that's an interesting question! In my vampire!Tim/werewolf!Jason verse and the accompanying fic, Tim drinks almost exclusively off of Jason because a) Jason loves it and b) Tim would near-starve himself otherwise :') (and he kind of does anyway, Jason has to bully him into feeding). So the only blood inside Tim at any given moment is usually Jason's original blood anyway. But can Tim give that blood back in an emergency?

tldr: yes, under certain conditions. lol

My reply was getting long because this kind of speculating is my favorite game to play, so if you're curious about what those conditions are and how I reached that conclusion, more details are under the cut:

In this verse, Jason is the kind of werewolf who doesn't have a lot of control/retained personality when he shifts, but he DOES have a lot of meta powers. (As a treat for becoming a mindless, violent monster lol ur welcome Jay)

One of those powers includes rapid healing ala deadpool/wolverine (unless the wound is inflicted by silver, ancestral or otherwise) so it would be remarkably difficult for Jason to reach the point where he even needs a blood transfusion. But let's consider that worst case scenario, in which Jason has suffered enough silver-inflicted wounds that his healing factor breaks and he needs blood, yesterday. Wuh oh.

Tim is the #1 candidate to consider for a Jason blood transfusion because that's his gamer fuel of choice - but for Tim to be a viable donor, it would depend on the length of time it's been since Tim drank from Jason, and how much. They're on a time limit because Tim's body doesn't replenish blood on its own, he has to steal it.

Brace yourself for the suspect use of rough science facts in the middle of supernatural fantasy speculation about vampire/werewolf AUs, lmao

So supposing Jason has about 12 pints/5.7 L of blood in total, he could lose maybe 5 pints/2.4 L of blood at a time without dying (and that's a high estimate, he'd start going into shock way before that lmao), AND it would take him weeks to restore that blood - if he were human.

Luckily for Tim, he can steal quite a bit from Jason without killing him because of the handy dandy werewolf healing factor that restores Jason's blood almost as fast as Tim's dusty ass can absorb it. (Tim's veins @ Jason's blood: 𝔪𝔬𝔦𝔰𝔱𝔲𝔯𝔦𝔷𝔢 𝔪𝔢). Unluckily for Tim (and Jason), Tim has about a zillion hangups over drinking that much all at once. Aw.

A brief google search tells me that in an average human body, red blood cells live about 120 days. For simplicity, we'll say that Tim being a vampire and having weird vampire powers counteracts Jason being a werewolf and his blood having weird werewolf properties - so when Tim is full (and I mean full) of Jason's blood, he's good for somewhere just under that 120 days.

The blood isn't immediately starving in Tim's stupid vampire body because it's strong, sexy werewolf blood; it stays hydrated for a million years and could thrive like a dandelion in a crack in the sidewalk, let alone a perfectly good, albeit abandoned, vascular system. (Jason's blood @ Tim's veins: 𝒾𝓉'𝓈 𝒻𝓇𝑒𝑒 𝓇𝑒𝒶𝓁 𝑒𝓈𝓉𝒶𝓉𝑒)

That being said, Tim starts getting very hungry near the end of that time frame as the blood is used/dies, and that time frame shrinks every time he bleeds (which is often, RIP Tim). But he'd still have a solid month or so of healthy, viable Jason blood pumping through his undead ticker. (unless Tim gets REALLY beat up lol, which is not unlikely OTL)

SO all this to say: can Tim give it back?

I would say yes, IF Tim has fed recently, and he's fed A LOT. Otherwise, he just straight up might not have the blood to give anymore because his stupid husk of a body already used it all.

If he tried to give Jason blood around the time he's getting hungry again, when Jason's blood is on it's last legs after sustaining an active vampire without reinforcements for weeks to months, it wouldn't be as effective as a blood transfusion from someone who can make their own blood and therefore has a fresher supply.

tldr (again lol); Tim could become a blood donor for Jason, but only once he's regularly letting himself drink from Jason, and drinking until he's full.
