SPOILERSTinker (Elfhome, Book 1)
by Wen Spencer
No quote cause I have misplaced the book and just want to move on. Tinker is the story of a girl genius(Tinker) who lives in Pittsburgh. A Pittsburgh that bounces between Earth and a planet (?) called Elfhome. She's (a bio engineered) human until she sleeps with an elf who uses magic and his sperm to turn her into an elf as well. Yup. That happens. She's super smart so people are after her to create more portals that will transfer them between worlds. Or something. I wasn't very happy with this book after the transformation sex so I will admit to checking out after that. There's also a lot of instances where male characters are really pushy and rape-y scenarios. It was not a fun book at all.
