From the bestselling author of The Room in the Attic comes a family's desperate race against time as one terrifying moment unravels into a living nightmare after a mother discovers her daughter is missing—and hasn’t been seen in weeks.

You'll do anything to get your daughter back ...

Lauren can't wait to see her daughter again, to pick her up from university at the end of her first term. But when she arrives at her hall and knocks on the door to her room, a stranger opens it.

At first, Lauren thinks she must have the wrong room, or the wrong floor. Maybe even the wrong building.

But she soon realizes the truth: Evie's not there. She hasn't been there for weeks. So where is she?
