After surviving horrific conditions in the Maze, Thomas is entrapped, along with nineteen other boys, in a scientific experiment designed to observe their responses and gather data believed to be essential for the survival of the human race. The group has two weeks to cross through the Scorch -- the most burned-out section of the world. And the observers will continuously adjust the variables and stack the odds against them.

Before WICKED was formed, before the Glade was built, before Thomas entered the Maze, sun flares hit the earth and mankind fell to disease.
