Synopsis
For Sam Ryan, life began at the age of fourteen. She has no memory of her parents or her past. All she has is a crayon drawing of a woman with the word "Mommy" scrawled underneath in childish handwriting.

For the ten years Sam's been with the State Police, she's used their resources to search for any clues to her identity. But it's as if all mention of her family has been deliberately wiped off the system, and no one seems to know why.

Everything changes the night she agrees to meet her missing partner, Jack, and barely survives his attempt to kill her. Charged with his murder and suspended from the force, Sam finds herself accepting help from Gabriel Stern--a shapeshifter with secrets of his own.

As Sam delves into her partner's death, she discovers more than she ever bargained for. Because not only is her partner very much alive, but he's involved in an organization that plans a war on the human race. Worse, someone knows the truth about Sam's past, and it appears that they'd rather see her dead than have her uncover it.

The deeper she digs, the more the danger grows. It soon becomes clear that the key to surviving the present lies in unraveling the threads of her past—and in discovering not just who she is, but what she is...
