When Thomas wakes up in the lift, the only thing he can remeber is his first name. He has no recollection of his parents, his home, or how he got where he is. His memory is blank.
But he's not alone. When the lift's doors open, Thomas finds himslef surrounded by kids who welcome him to the Glade, a large expanse enclosed by stone walls.
Just like Thomas, the Gladers don't know why or how they got to the Glade. All they know is that every morning, for as long as anyone can remember, the stone doors to the maze that surrounds them have opened. Every night, for just as long, they've closed tight. Every thirty days a new boy is delivered in the lift. And no one wants to be stuck in the Maze after dark.
The Gladers were expecting Thomas's arrival. But the next day, a girl is sent up—the first girl ever to arrive in the Glade. And more surprising yet is the message she delievers. The Gladers have always been convinced that if they can solve the maze that surrounds the Glade, they might find their way home... wherever that may be. But it's looking more and more as if the Maze is unsolvable.
And something about the girl's arrival is starting to make Thomas feel different. Something is telling him that he just might have some answers—if he can only find a way to retrieve the dark secrets locked within his own mind.
A boom exploded through the air, making Thomas jump. It was followed by a horrible crunching, grinding sound. He stumbled backward, fell to the ground. He wouldn't have believed it if he hadn't seen it for himself. The enormous stone wall to the right of them seemed to defy every known law of physics as it slid along the ground, throwing sparks and dust as it moved, rock against rock. The crunching sound rattled his bones. He looked around at the other openings. On all four sides of the Glade, the right walls were moving toward the left, closing the gap of the Doors.
Then on final boom rumbled across the Glade as all four Doors sealed shut for the night.
