Hello and welcome to my pinned post.

I am Piper, and I mostly write Transformers fanfic on AO3. Bluestreak is my favourite character, and he features very prominently in a lot of my stories.

Because I have 100+ (!) stories on AO3, I wanted to do a little bibliography of a few of the stories I am most proud of. 🤗 Note the ratings and tags on these if you decide to read them, please!

I divided the list into shorter fics and longer fics.

Shorter Fics (10,000 words or less)

Do You See What I See? (Rated G, Bluestreak/Hound). I like this one because I leaned heavily into the alien aspect of the Cybertronians, which meant I got to do some fun worldbuilding.

Datastream (Rated Teen, Jazz/Prowl). I got to do (kinda) spoken-word poetry in this story, sketching out how Blaster and Prowl's minds might merge and work as one. I liked how it turned out. It has an illustration done by @myladraws!

Debts (Rated Mature for body horror, Smokescreen & Prowl). I love horror, and I played with tension and anticipation in this one. I have been told this is one of my most disturbing fics, so keep that in mind!

Longer Fics (10,001+ words)

Mind, Body, and Soul (Rated Explicit, Barricade/Bluestreak/Prowl/Smokescreen in various configurations). This is the story I am the most proud of, and it's also the longest by far. It is a sprawling tale about love and betrayal and forgiveness and perseverance, and I am so so happy with how it came out. It has fanart done by @/Klick_tack on Twitter!

The Spark Remembers (Rated Teen, Bluestreak/Hound and Bluestreak/Prowl.) I had fun weaving Bluestreak's past into what his new future was, and I loved the screaming from the readers at the reveal. 😅 This was a Big Bang story so it has artwork from @chaoswolf12 and @tfadi!

The Colour of Your Optics (Rated Explicit, Bluestreak/Sunstreaker) This is a story in my "there's a dating app called Sparkr" series with a bunch of loosely-related fics, but this one in particular is sickeningly and adorably sweet. In my opinion. :)

My ask box is almost always open, so if you want to come in and scream at me about robots, please do. ^.^
