Fourteen-year-old Emily Prince has just moved to Windsor, Ontario. As if trying to make friends in a new school is not stressful enough, Emily's abusive mother does not care if she ever fits in. Emily is her victim.

With a vanished father and a mother who hates her, it seems there is no one who can rescue Emily from her fate-until she meets her neighbor across the street. Dean Bouche is drop-dead gorgeous and blessed with an intoxicating laugh. Better yet, he attends St. Gervase's Catholic High School, just like her. As Emily and Dean begin a complicated relationship, her secret life is exposed and she discovers that Dean is not who he appears to be. But when all her new friends suddenly become obsessed with the bird-like birthmark she sports on her shoulder and Dean goes missing, Emily suddenly realizes that something is wrong-very wrong.

Shapeshifter's Mark is the gripping story of one girl's struggle to overcome abuse as she is unwittingly immersed into a strange new world where she soon discovers the truth about her destiny.
