Katherine Powers is terminally ill. Her husband Adam is an innovative surgeon who promises he can save her.
It begins with a choice: wait for the inevitable, or take a chance at living with an experimental surgery. Katherine chooses life, even if there are risks involved. After all, she's not ready to die, and Adam insists he will get it right this time. What does she have to lose? The last thing Katherine hears before the anesthesia kicks in, is Adam's voice...
But when Katherine wakes up post-surgery, she's in an unfamiliar hospital room and Adam has vanished. This isn't the body she chose. The psychological toll of seeing a stranger in the mirror is greater than she ever imagined. Hurt, angry, and left to fend for herself, Katherine must find a way to survive. She'll assume the life of her host while she hunts for Adam. And she will find him. But who can she trust...and can she even trust herself?
