From the bestselling author of Alice, three women find themselves trapped inside fictional worlds and must fight to survive in this ground-breaking, locked-room horror novel. One day Celia wakes up in a house that isn't hers with a husband she doesn't recognise and a little girl she's never seen before 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 in a gossipy small town, and a feud with a neighbour who ends up dead - is not hers. Allie and her friends travel to a remote cabin in the woods for the weekend.
