The Maze Runner (book-1)

Thomas finds himself in a strange lift. He is in a glade with many other boys, and remembers nothing else but his name. Why is this strange maze called the Glade? Why are the odd metallic creatures called the Grievers? Why does the Glade seem to change each time they return? No one knows the answers to any of these questions. But the only thing that Thomas knows for certain is that in order to survive, he needs to run. On a fateful day, a girl joins them with a message. Everyone is left numbed by shock when they learn what it is. Hence begins the adventure of Thomas and his friends in the maze. The Maze Runner is followed by The Scorch Trials and The Death Cure. The current title has been adapted into a movie by 20th Century Fox.
