Fiona doesn’t remember going to sleep. But when she opens her eyes, she discovers her entire world has been altered-her house is abandoned and broken, and the entire neighborhood is barren and dead. Even stranger is the tattoo on her right wrist-a black oval with five marks on either side-that she doesn’t remember getting but somehow knows she must cover at any cost. And she’s right.
