Sometimes what you don’t know can hurt you. In Riley Harper’s case, it’s what she says she can’t remember. Nearly a decade ago, Riley was the suspect in a murder investigation that destroyed her life and drove her into a psychiatric facility. Locked away for years, she was always guilty in the eyes of an unforgiving public.

Now, after being released, all she wants is a fresh start, but the effort stalls when she becomes fixated on her new neighbor’s extravagant life. She can’t stop watching Samantha Light. And it’s curiously satisfying.

For now, at least.

Because there’s one more thing Riley doesn’t know. And this time it may not just hurt her—it could kill her.

In this intense psychological thriller from Andrew E. Kaufman, author of Twisted, a woman besieged by her past spins deeper into turmoil and down a slope that may lead her to madness.
