In 'The Maze Runner,' Thomas awakens to find himself in an elevator with no memory of his past, save for his name. He emerges into the Glade—a verdant open space surrounded by towering stone walls—with other boys who share his amnesia. Every day, the Maze beyond the walls shifts and changes, and every night, it closes off. No one has ever escaped it alive. The routine of their lives is shattered with the arrival of the first girl, Teresa, who carries a message that will change everything: Remember. Survive. Run. Together, Thomas and the other 'Gladers' must unravel the mystery of their circumstances while battling the Grievers—deadly creatures that roam the Maze—if they ever hope to escape.
