Lies, secrets, and obsessive motherly love collide in a chilling novel of psychological suspense by a Washington Post bestselling author.

Press, tap, refresh...

When Autumn Carpenter stumbles upon the social media account of the family who adopted her infant daughter years ago, she finds herself instantly drawn into their picture-perfect existence. From behind a computer screen, Autumn watches Grace's every memory, from birthdays to holidays to bedtime snuggles. But what starts as an innocent fascination soon spirals into an addictive obsession that comes to a screeching halt the day the McMullen family closes their Instaface account without so much as a warning.

Frantic and desperate to reconnect with her daughter, Autumn applies for a nanny position with the McMullens, manipulating herself into Grace's life under false pretenses. It's only then that Autumn discovers that pictures lie, the perfect family doesn't exist-and beautiful people? They have the ugliest secrets.
