In a near-future New York, Chester Owens — a tall, lumbering sixteen-year-old with severe social anxiety — clings to routine and tries to remain invisible. Abandoned by his parents as a baby, all Chester knows is Greendale, a secretive, locked-down facility where he and his classmates are taught to cope with their mental illnesses.
But the facility is not what it seems. Run by the powerful and sinister Leto corporation, it thrives under the strict rule of Claire Steinfeld. Where did these students really come from? What’s Leto’s plan for them? A group of activists and whistleblowers are about to expose Leto from within, and Chester will learn how unique he really is.
