From the author of Behind Her Eyes, now a Netflix Original Series hit

"Sarah Pinborough is about to become your new obsession." —Harlan Coben

Lisa is living a lie and everyone is about to find out.

Lisa lives for her daughter Ava, her job and her best friend Marilyn.

But when a handsome client shows an interest in her, Lisa starts daydreaming about sharing her life with him, too. Maybe she’s ready now. Maybe she can trust again. Maybe it's time to let her terrifying secret past go.

But when her daughter rescues a boy from drowning and their pictures are all over the news for everyone to see, Lisa's world explodes.

As she finds everything she has built threatened, and not knowing who she can trust, it's up to Lisa to face her past in order to save what she holds dear.

But someone has been pulling all their strings. And that someone is determined that both Lisa and Ava must suffer.

Because long ago Lisa broke a promise. And some promises aren't meant to be broken.
