When sixteen-year-old May gets the chance to start over in the small town of Lockwood, she's determined not to let anything ruin it. Not her chronic exhaustion, not the enigmatic boy she's drawn to, and definitely not the truth about what happens when she falls asleep. But then a missing student turns up dead - and May recognizes the body from a dream. Thrown into a deadly mystery, May is forced to confront her unwanted ability: every time she sleeps, she's dragged into the dreams of those around her. Disturbing enough on a regular night, these dreams take a terrifying turn as it becomes clear there is a serial killer haunting the streets of Lockwood. Soon, those she's close to are being targeted and May is running out of time to harness her gift-her curse-to stop the murders. Because the killer isn't going to wait. In fact, they're just getting started.
