September 2024 reads

[loved liked ok nope dnf bookclub*]

Agnes Grey • The Empire Wars • Vita Nostra • 17776: What Football Will Look Like in the Future • Somewhere Beyond the Sea • A Sorceress Comes to Call • Tress of the Emerald Sea • Long Live Evil • Books Do Furnish a Room • A Sunny Place for Shady People • Mansfield Park* • The Butcher of the Forest

I read 12 books in September, though several were short (and one was a... multimedia experience? What are we calling 17776 anyway?) I've been feeling a little burnt out on ARCs and @bellasbookclub -screening reads, so after the first week I took a break from those. Just as well, because I was once again abruptly drowning in new releases! Luckily only four library holds were ready at once this month. Have I learned my lesson about hold requests? Not at all.

Agnes Grey ★★★☆☆ - I enjoyed the semi-autobiographical "being a governess SUCKS" parts of this book (that bird scene holy shit), but I think I would have liked it better with a less milquetoast love interest.

The Empire Wars ★☆☆☆☆ - Oooooof. I thought there was no way any of the books in my self-imposed Bombed Books Week Challenge could be worse/less enjoyable than Hurricane Wars and TGUWG, but this one took the cake. There's "I wrote this at age 15" (impressive) and then there's "I wrote this at age 15" (and it shows/and I can't believe multiple literate adults in the publishing industry greenlit it.) "Hazen Creed" is the new Xylen Rayder or whatever the 4th w!ng guy's name is

Vita Nostra ★★★★☆ - I was promised weird shit and this book delivered! You don't get it? Good news, nobody gets it, we're literally just vibing

17776: What Football Will Look Like in the Future ★★★★☆ - Some interesting themes and a lot of fun! (I liked when it started zooming in on Denver and I was like wait a fucking second is that Ball Arena??)

Somewhere Beyond the Sea ★☆☆☆☆ - Yeah, I can't lie, this was a hateread. No other series makes me feel more like the child in "The Emperor's New Clothes." Like, people enjoy this?? Adults?? Adults think this is good storytelling??? I'm not even trying to be mean (well, maybe a little), I'm genuinely baffled. Remember when I described Book 1 as "like driving behind a Coexist bumper sticker for several hours"? Book 2 is like driving behind a Coexist bumper sticker while also listening to someone read you the worst parts of Harry Potter and the Order of the Phoenix but in Kindergarten Teacher Voice, and for even more hours. Lesson learned: I have got to stop picking these up imagining I'll somehow see the appeal this time.

A Sorceress Comes to Call ★★★★★ - My first ever T. Kingfisher! I've always been hesitant to believe the hype, but to my pleasant surprise, this one was fantastic. The stakes, the characters, the evil fucking horse had me on the edge of my seat. Pretty crazy when the interior of a book lives up to its gorgeous cover. Had to rush out and buy this one from my local bookstore!

Tress of the Emerald Sea ★★★★☆ - Fun and cute! The main draw is definitely the silly writing style.

Long Live Evil ★★★★☆ - Took its time to get going, but the second half really gained momentum. This book's main flaw is that it isn't In Other Lands, but it's nevertheless nice to see SRB cut loose and write a silly isekai/harem trope pastiche that is somehow also a thoughtful cancer survivor catharsis.

Books Do Furnish a Room ★★★☆☆ - When I picked up this coffee table book at the library on a whim, nothing could have prepared me for its Caricature Of British Aristocracy tone. Like at one point this author calls Africa "a country." Seriously, they do not edit the text of these things. Pretty pictures, though.

A Sunny Place for Shady People ★★★★☆ - I'll read Mariana Enriquez's grocery list. On the whole, Sunny Place wasn't as gripping as Our Share of Night, but some of its individual stories (it's an anthology) stood out—I loved the nuance of My Sad Dead and the nightmare fuel of Black Eyes! Some choice body horror in here.

Mansfield Park ★★★☆☆ - A reread for Bella's Book Club's September discussion! I think I liked it better this time around? I definitely noticed more of the character arcs. I like that this is lowkey the messiest Austen. [Community episode voice] now THIS is a man who KNOWS HOW TO MARRY HIS COUSIN

The Butcher of the Forest ★★★★☆ - I'm slowly working my way through Tordotcom novellas and so far they all slap. This one had such an interesting ending, ngl I'm having to quash the Fanfic Urge about it!

DNFs: None, but boy would I have dropped The Empire Wars like a hot potsticker on about page 2 if it wasn't the last (or second-to-last, if you count control group Crown of Starlight) book in my own challenge.

September superlatives

tbh a lot of these books could swap spots with each other. I'll definitely be rereading Sorceress, and probably LLE when the next book in its series comes out!

Next up:

I still haven't gotten around to Crown of Starlight, so it looks like I'll be finishing up my Bombed Books Week Challenge in October. Nor have I gotten to my ARCs of Ruin Road or Sundown in San Ojuela, so those are both on this month's agenda. My current read is A Dark and Drowning Tide (I seem to be the one reader on the planet who didn't much like A Far Wilder Magic, but I like to give authors a second chance, and that cover + the fact that they're lesbians, Harold got to me.) I'd love to squeeze in a King in Yellow reread if possible, and our Bella's Book Club pick this month is Murder on the Orient Express, so...perfect October rereads? I'm kinda stoked!

Brazil reinstates tax break for chemicals, incentivises natgas-based fertilizers plants

The Brazilian government has reinstated a tax break for the chemicals industry after intense lobbying from the sector.

The new regulation provides for additional credits for companies that invest in expanding their production capacity or in new plants that use natural gas to produce fertilizers.

The reinstated Special Regime for the Chemical Industry (REIQ) is to lower the PIS/COFINS tax rate that the chemical industry pays for inputs within the xylenes chain, including naphtha, benzene, propene, ethene, toluene, and cumene.

PIS and COFINS are imposed on the Brazilian entity or individual (the importer of goods or services) and should apply to the import of services at the rates of 1.65% and 7.6%, respectively.

As Los Angeles battles recent wildfires, air quality across the region has plummeted to hazardous levels. Based on authoritative recommendations, many have turned to air filters and purifiers as a defense against smoke pollution. But what if these solutions are not as protective as suggested? It turns out there are widespread misconceptions about wildfire smoke and its hazards, as well as the effectiveness of air filtration in protecting human health against wildfire smoke because this has been an understudied and consequently overlooked area of research. A scientific paper by Metalmark researchers uncovers critical flaws in current filter technologies and their assessment when it comes to capturing dangerous wildfire smoke particles. "There are a number of misconceptions about the size and behavior of particles generated by wildfires," explains Sissi Liu, CEO and co-founder of Metalmark Innovations. "This leads to a false sense of security when recommending filters tested using methods that don't account for the unique properties of smoke." The recent fires in Los Angeles have blanketed the region in thick smoke. The South Coast Air Quality Management District has reported PM2.5 levels up to 5 times the federal standard, prompting warnings to stay indoors. Understanding Wildfire Smoke and PM2.5 Wildfire smoke consists of fine particulate matter (PM) known as PM2.5, which includes particles smaller than 2.5 microns in diameter — approximately 1/30 the diameter of a human hair and smaller. While PM2.5 is a regulatory benchmark, this characterization fails to convey the size distribution of smoke particles. Practically all wildfire smoke particles are much smaller, averaging about 0.1-0.3 microns — roughly 1/350 the diameter of a human hair and smaller. This distinction is critical because smaller particles carrying toxic chemicals are more harmful, penetrating deep into the lungs and more capable of entering the bloodstream. Key Misconceptions About Wildfire Smoke Misconception #1. Smoke Particles Are Larger Than 1 Micron Wildfire smoke particles are predominantly submicron in size, forming as ultrafine particles (UFPs) immediately during combustion. Over tens of minutes, these particles stabilize between 0.1-0.3 microns, allowing them to travel vast distances without significant size changes. This stability means that harmful smoke particles from fires in Los Angeles can affect air quality across the US West Coast and the rest of the US. Misconception #2. Wildfire Smoke Is Just Like Any Other PM2.5 Unlike urban PM2.5, which often originates from traffic and industrial emissions, wildfire smoke is composed mainly of organic carbon compounds. Fires in the wildland-urban interface (WUI) include the combustion of biomass, building materials, vehicles, electronics, batteries, and more. They introduce additional toxins, including hydrogen cyanide, hydrogen fluoride, hydrogen chloride, isocyanates, dioxins, furans, chlorine, various toxic organic compounds (e.g., benzene, toluene, xylenes, styrene, formaldehyde), heavy metals (e.g., lead, chromium, cadmium, arsenic), and polycyclic aromatic hydrocarbons (PAHs). While some toxins, such as highly volatile formaldehyde, are transported in gaseous form, many of these toxic substances hitch a ride on smoke particles, often reported at diameters 200-300 nm or below, making them hazardous over long distances. Moreover, wildfire smoke aerosols are dynamic, containing semi-volatile organic compounds that can evaporate and react to form secondary pollutants, further degrading air quality and posing ongoing health threats. Smoke is even known to spread pathogens, contributing to rising cases of Valley Fever, for example. Misconception #3. Smoke Is Harmless If You’re Far from the Fire Smoke’s impact from large-scale extends far beyond the immediate vicinity of the fire. During the 2023 Canadian wildfires, for example, smoke traveled thousands of miles and caused hazardous air quality as far away as New York City and Atlanta. Despite the distance, the particle size and toxicity remain largely unchanged, leading to increased respiratory and cardiovascular health issues in affected regions. Research shows that faraway smoke increases cardiopulmonary disease and is associated with up to 1000-fold the premature deaths of the fires themselves. Misconception #4. Staying Indoors Provides Adequate Protection Many believe that staying indoors is a sufficient safeguard against wildfire smoke. However, smoke particles infiltrate buildings through gaps, ventilation systems, and even closed windows. Additionally, indoor air quality can degrade due to formaldehyde, ozone, and other chemicals — common byproducts of wildfires that penetrate indoors. Misconception #5. Current MERV-13 and HEPA Filters Provide Sufficient Protection While MERV-13 and HEPA filters are touted as effective solutions, they have limitations: Suboptimal Performance for Submicron Particles: Most HVAC filters, including MERV 13 and higher grades, are the least effective at capturing particles in the 0.1-0.3 micron range — precisely the size of wildfire smoke particles.

While some toxins, such as highly volatile formaldehyde, are transported in gaseous form, many of these toxic substances hitch a ride on smoke particles, often reported at diameters 200-300 nm or below, making them hazardous over long distances. Moreover, wildfire smoke aerosols are dynamic, containing semi-volatile organic compounds that can evaporate and react to form secondary pollutants, further degrading air quality and posing ongoing health threats. Smoke is even known to spread pathogens, contributing to rising cases of Valley Fever, for example.

As Los Angeles battles recent wildfires, air quality across the region has plummeted to hazardous levels. Based on authoritative recommendations, many have turned to air filters and purifiers as a defense against smoke pollution. But what if these solutions are not as protective as suggested? It turns out there are widespread misconceptions about wildfire smoke and its hazards, as well as the effectiveness of air filtration in protecting human health against wildfire smoke because this has been an understudied and consequently overlooked area of research. A scientific paper by Metalmark researchers uncovers critical flaws in current filter technologies and their assessment when it comes to capturing dangerous wildfire smoke particles. "There are a number of misconceptions about the size and behavior of particles generated by wildfires," explains Sissi Liu, CEO and co-founder of Metalmark Innovations. "This leads to a false sense of security when recommending filters tested using methods that don't account for the unique properties of smoke." The recent fires in Los Angeles have blanketed the region in thick smoke. The South Coast Air Quality Management District has reported PM2.5 levels up to 5 times the federal standard, prompting warnings to stay indoors. Understanding Wildfire Smoke and PM2.5 Wildfire smoke consists of fine particulate matter (PM) known as PM2.5, which includes particles smaller than 2.5 microns in diameter — approximately 1/30 the diameter of a human hair and smaller. While PM2.5 is a regulatory benchmark, this characterization fails to convey the size distribution of smoke particles. Practically all wildfire smoke particles are much smaller, averaging about 0.1-0.3 microns — roughly 1/350 the diameter of a human hair and smaller. This distinction is critical because smaller particles carrying toxic chemicals are more harmful, penetrating deep into the lungs and more capable of entering the bloodstream. Key Misconceptions About Wildfire Smoke Misconception #1. Smoke Particles Are Larger Than 1 Micron Wildfire smoke particles are predominantly submicron in size, forming as ultrafine particles (UFPs) immediately during combustion. Over tens of minutes, these particles stabilize between 0.1-0.3 microns, allowing them to travel vast distances without significant size changes. This stability means that harmful smoke particles from fires in Los Angeles can affect air quality across the US West Coast and the rest of the US. Misconception #2. Wildfire Smoke Is Just Like Any Other PM2.5 Unlike urban PM2.5, which often originates from traffic and industrial emissions, wildfire smoke is composed mainly of organic carbon compounds. Fires in the wildland-urban interface (WUI) include the combustion of biomass, building materials, vehicles, electronics, batteries, and more.

Current MERV-13 and HEPA Filters Provide Sufficient Protection While MERV-13 and HEPA filters are touted as effective solutions, they have limitations: Suboptimal Performance for Submicron Particles: Most HVAC filters, including MERV 13 and higher grades, are the least effective at capturing particles in the 0.1-0.3 micron range — precisely the size of wildfire smoke particles. Furthermore, their efficacy is not generally assessed for particles in the
