After bouncing from foster home to foster home, Magdalene Mae is transferred to what should be her last foster home in the tiny town of Silver City, New Mexico. Now that she's eighteen and has only a year left in high school, she's determined to stay out of trouble and just be normal.

Agreeing to go to the prom with Bridger O'Connell is a good first step. Fitting in has never been her strong suit, but it's not for the reasons most people would expect-it all has to do with the deep secret that she is a shape shifter. But even in her new home danger lurks, waiting in the shadows to pounce. They are the Skinwalkers of Navajo legend, who have traded their souls to become the animal whose skin they wear-and Maggie is their next target.
