The Scorch Trials

Thomas was sure that escape from the maze meant he and the Gladers
would get their lives back. But no one knew what sort of life they
were going back to. The earth is a wasteland. Government and
order have disintegrated and now Cranks, people driven to murderous
insanity by the infectious disease known as the Flare, roam the
crumbling cities hunting for their next victim ... and meal. Thomas
can only wonder - does he hold the secret of freedom somewhere
in his mind? Or will he forever be at the mercy of WICKED? The
pulse-pounding sequel to The Maze Runner.
