With her only link to humanity gone, Lyn must tame the predator inside her or risk becoming what she hates most. Creatures are out in the world, and in Cedar Oaks they outnumber the humans, only you can't tell by looking at them. After the death of her mother, Lyn Davis, a sophomore in high school, should be taking care of herself. Except she can't even stand up to the school bully. She is faced with the choice of making a new life with the nosy neighbor across the street, whom she doesn't trust, or finding the man who walked out on her mother the day she was born. Together with her best friend, who is convinced that Lyn is more than simply human, Lyn has forty-eight hours to find out who her father is or have the choice taken away from her. But when solving one problem leads to a dangerous discovery, Lyn is forced to turn to an unlikely ally and decide what it means to be Becoming Creature.
