From the author of the Reese’s Book Club Pick and the New York Times bestseller Wrong Place Wrong Time comes a new heart-stopping thriller in which a missing-person case unravels deeper, darker secrets that lead a detective to an impossible moral choice.

Not everyone who is lost should be found…

22-year-old Olivia has been missing for one day…and counting. She was last seen on CCTV, entering a dead-end alley. And not coming back out again.

Julia, the detective heading up the search for Olivia, thinks she knows what to expect. A desperate family, a ticking clock, and long hours away from her husband and daughter. But she has no idea just how close to home this case is going to get.

Because the criminal at the heart of the disappearance has something she never expected. His weapon isn’t a gun, or a knife: it’s a secret. Her worst one. And her family's safety depends on one thing: Julia must NOT find out what happened to Olivia - and must frame somebody else for her murder.

If you find her, you will lose everything. What would you do?

This clever and endlessly surprising thriller is laced with a clever look at family and motherhood, and cements Gillian McAllister as a major talent in the world of suspense and a master of creating ethical dilemmas that show just how murky the distinction between right and wrong can be.
