Mallory killed her boyfriend, Brian. She can't remember the details of that night but everyone knows it was self-defense, so she isn't charged.

But Mallory still feels Brian's presence in her life.

Is it all in her head? Or is it something more? In desperate need of a fresh start, Mallory is sent to Monroe, a fancy prep school where no one knows her . . . or anything about her past. But the feeling follows her, as do her secrets. Then, one of her new classmates turns up dead. As suspicion falls on Mallory, she must find a way to remember the details of both deadly nights so she can prove her innocence-to herself and others.

In another riveting tale of life and death, Megan Miranda's masterful storytelling brings readers along for a ride to the edge of sanity and back again.
