When the elevator doors open, Thomas gets another surprise; a group of boys welcome him to the Glade, a large, open expanse surrounded by stone walls. None of the boys knows why they are there; they just know that another new boy arrives every thirty days. But the day after Thomas arrives, the pattern is broken; someone else comes to the Glade. And, for the first time, that someone is a girl. The message she delivers makes Thomas think that they must escape the Glade before time runs out. Does Thomas’s lost memory hold the key to escape?
