The Stray Lamb, by Thorne Smith. Mr. T. Lawrence Lamb, a staid banker, is transformed into lots of animals.
Transmutation NOW!, by Phil Geusz. Actually, a lot of books by Phil Geusz about men turning into rabbits, or horses. The Book of Lapism, Descent, Freedom City, etc.
I hear the Altered States anthology is getting closer to release, but it might not be until Anthrocon. It will feature a collection of transformation stories. Phil Geusz probably has several stories in there; transformation has been his thing for years
My novel Huvek has the main human character becoming nonhuman by the end. Might be what you’re looking for, though transformation is not the theme of the book.
Also, I have a TF novella coming out this year from Red Ferret Press. THE GOAT: Building a Perfect Victim. As the release date gets closer, maybe I can arrange a pdf or something?
You might want to check out my upcoming paranormal sci-fi thriller, first in a werecat family saga. ALWAYS GRAY IN WINTER releases August 10, 2017 from Thurston Howl Publications. From the back cover copy:
“The modern day remnant of an ancient clan of werecats is torn apart by militaries on three continents vying to exploit their deadly talents. Born in an ethnic Chicago neighborhood following her family’s escape from Cold War-era Poland, were-lynx Pawly flees underground to protect her loved ones after genetically-enhanced soldiers led by rogue scientist and rival werecat Mawro overrun her Navy unit in the Gulf of Oman. Pawly’s family seeks her out in a desperate gambit to return their ancestral homeland and reconcile with their estranged kinsmen. But when her human lover arrives to thwart Mawro’s plan to weaponize their feral bloodlust, Pawly must face a daunting choice: preserve her family secrets and risk her lover’s life or chance her true nature driving him away forever.”

Forgot to check back in with you but my friend and Thurston Howl Publication’s stablemate Wolphicorn’s post reminded me…my werecat book is out now too from THP! Hope you’ll enjoy it.
