'A gloriously bonkers final twist' - The Sunday Times

'Take the propulsive darkness of Gone Girl, the prolific output of Colleen Hoover, and the addictive twists of Harlan Coben, and you have something close to Freida McFadden.' - The Independent

'Intimidatingly prolific' - The Sunday Times

From #1 Sunday Times bestselling author Freida McFadden comes a gripping psychological thriller about a YouTube sensation who has secrets hidden offline that might be enough to destroy her.

***

Everyone has secrets. But some are worse than others…

Influencer and baking sensation April Masterson knows the secret to the perfect gooey brownies. Or how to make key lime squares that will melt in your mouth. But if you keep watching her offline, you may find out some other secrets about April. Secrets she'd rather you didn't know.

Like… Where did her son go when he snuck out late at night? What was she doing with the local soccer coach behind fogged windows?

And what's buried in her backyard?

April's secrets are enough to destroy her.

I'll make sure of that.

The inimitable Freida McFadden peels back the layers of a seemingly flawless life to expose a picture of obsession, deception, and the quiet menace that waits just beyond the frame - with shocking twists that will keep you hooked to the last page.
