Thomas was sure that escaping the labyrinth would mean freedom for him and the Glades, but Wikid hadn't got it all out for them yet. The second phase, the scorching earth phase, has begun. The Glades have two weeks to cross the Burning Land, the most devastated part of the world. And Kidd was keen to put obstacles in front of them and create difficulties for them

make their mission impossible.

Now, there are others who depend on the death of the Glades for their survival, and they will fight to survive.

Friendship will be tested, promises broken, and all bets lost.
