From the bestselling author of Alice, three women find themselves trapped inside fictional worlds and must fight to survive in this groundbreaking locked-room thriller.

Celia wakes up in a house that isn't hers. She doesn't recognise her husband or the little girl who claims to be her daughter. She tries to remember who she was before, because she is certain that this life - the little family-run restaurant she owns, the gossipy small town she lives in - is not her own. Allie is supposed to be on a fun weekend trip - but then her friend's boyfriend unexpectedly invites the group to a remote cabin in the woods. The cabin looks recently assembled and there are no animals or other life anywhere in the forest.

Nothing about the place seems right. Then, in the middle of the night, someone bangs on the cabin door... Maggie, along with twelve other women, wakes up in a shipping container with the number three stamped on the back of her T-shirt. If she wants to see her daughter Paige again, Maggie must complete The Maze - a deadly high-stakes obstacle course. Three women. Three stories. Only one way out...
