Doppelganger

Doppelgangers are monsters, hardwired for murder.
They are not supposed to have doubts, but this one does. He wishes he could be different. More human, maybe. But even that can't stop him from killing people so he can take their places and live their lives. He has to do it; it's who he is.
But when the doppelganger murders a small-town teenager, assumes his shape, and takes over his life, he's shocked by the world he steps into. Engulfed in a whirlwind of peer pressure, messy family dynamics, and a provocative relationship with a beautiful girl, he quickly learns that there's more than one way to be human, and many ways to be a monster.
Told in the tortured voice of a most extraordinary teen, this contemporary gothic romance brews a captivating combination of violence, desire, and atonement. Here is the story of a monster yearning for a human life.
