In "The Kill Order", Thomas gets an operation for him to get the Swipe, so he can be sent in the maze with the other Gladers. Through the operation, Teresa is by his side the whole time, scared to what'll happen to her and Thomas, but calm, believing that WICKED will find a cure for the Flare for the sake of humanity.
In The Maze Runner, a 16 year old boy named Thomas wakes up in a lift with no memory except for his name. When the lift opens he is surrounded by other kids who also have no memory except their names. This place is called the Glade. The glade is surrounded by a maze with stone walls. Every morning, the doors to the maze open, every night they close. The gladers do not want to be stuck in the maze when the walls close, or they could be stung by hideous monsters called Grievers. In the middle of the book, the gladers lose protection because the walls stop closing. They must find a way out quickly. Thomas and Teresa eventually figure out a code to the maze. Thomas gets stung purposely by Grievers so he can remember his life before the maze. He learns that there is only one escape. Through the Griever hole. The Gladers make it through the Griever hole, losing half of their number, including Alby. They are greeted by someone who works for WICKED and Gally. Gally takes a knife and throws it at Thomas, but Chuck bravely takes the hit by jumping in front of Thomas. Thomas feels guilty because he had promised Chuck to get him out of the maze safely. Then a rescue team comes in and seemingly kill the WICKED member, rescuing the gladers.
In The Scorch Trials, Thomas and the other gladers find out the rescue was a hoax, and they travel 100 hundred miles of wasteland in 2 weeks to a safe haven for a cure to the flare. The flare is a disease that drives people to murderous insanity. It takes a really long time to start forming though. Will they make it to the safe haven in time? Or will they become victim of the flare? Read the book for answers.
In The Death Cure, WICKED does not give them a cure like they promised. They say there will be no more trials, the blueprint is almost complete....almost...... However WICKED tells the gladers that they are getting their memories back. But Thomas, Minho, and Newt refuse. Thomas already remembered enough from the Changing back in the Glade, that they can not be trusted.
