Lily wakes up inside a metal elevator with no memories. When the doors open, she finds seven boys living inside a massive enclosed settlement called The Yard. Beyond the Yard is an enormous shifting labyrinth. Nobody knows who built it. Nobody knows why they're there. Nobody remembers their lives before arriving. And every few weeks, another person used to arrive in the elevator. Until Lily. She is the eighth and final person. The moment she arrives, everything changes.
