The Death Cure by James Dashner is the third book in the Maze Runner series.
After the Scorch Trials, Thomas is taken into solitary confinement. After a few days, the Rat Man wants to talk to Thomas about the Scorch Trials and his friends. Janson gives the Gladers a chance to get their memories back. Thomas and his friends have to decide if they want to get their memories back or not.
I would recommend this book to people who have read and seen the first 2 books (Maze Runner and Scorch Trials) and movies. The events in this book tie in (and connect) to and with this book. The ending completely wrapped up the whole series.
