Book four in the blockbuster Maze Runner series that spawned a movie franchise and ushered in a worldwide phenomenon! And don't miss The Fever Code, the highly-anticipated series conclusion that finally reveals the story of how the maze was built! Before WICKED was formed, before the Glade was built, before Thomas entered the Maze, sun flares hit the earth, killing most of the population. Mark and Trina were there when it happened. They survived. But now a virus is spreading. A virus that fills humans with murderous rage. They're convinced that there's a way to save those who are left-if they can stay alive. Because in this new, devastated world, every life has a price. And to some you're worth more dead than alive. The end is only the beginning. The Maze Runner, Maze Runner: The Scorch Trials, and Maze Runner: The Death Cure are all now major motion pictures featuring the star of MTV's Teen Wolf, Dylan O'Brien; Kaya Scodelario; Aml Ameen; Will Poulter; and Thomas Brodie-Sangster. Also look for James Dashner's edge-of-your-seat MORTALITY DOCTRINE series!
