What would happens if Theresa and Aris never went into swapped Mazes? What if Theresa went into Maze B and Aris went into Maze A? When Ember finds herself in a chilled, confined, fast-moving box, she loses it. She doesn't know what to do, where she's going. She's lost. She's a nobody. She has no memory. When the top of the box is lifted up, many boys faces surround her. One year later, a boy named Thomas comes into the box just like everyone else. Confused, lost, no memory. Ember feels a strange connection with this new boy, unlike any other Glader. She must face what her body feels, finding the connection, and run there way out of the Maze. The day after Thomas comes up from the box, another boy arrives with a note in his hand. The note will change everything, and so will the boy. It's up the the Gladers to find out how to deal with it, and what to do.
