From the author of When I was your comes a spine-tingling new thriller about a mother's worst nightmare come true, when her teenage daughter goes to a sleepover and doesn't come back. Whitney had some misgivings when she dropped her increasingly moody teenage daughter, Amelia, off at Lauren's house. She'd never met the parents, and usually she'd go in, but Amelia clearly wasn't going to let something so humiliating happen, so instead Whitney waved to her daughter before pulling away from the little house with the roses in front. But when she goes back the next day, an elderly couple answers the door -- Amelia and Lauren aren't there, and this couple swears they never were, that she's at the wrong house. As Whitney searches for Amelia, she uncovers a trail of lies her daughter has told her -- from the Finsta account to rumors of a secret relationship. Does she really even know this girl she's raised? And Amelia's not the only one with secrets. Could Whitney's own demons have something to do with her daughter's disappearance, and can Whitney find her before it's too late?
