The Scorch Trials by James Dashner

The Scorch Trials picks up where The Maze Runner left off. The Gladers have escaped the Maze, but now they face an even more treacherous challenge on the open roads of a devastated planet.
And WICKED has made sure to adjust the variables and stack the odds against them.
Can Thomas survive in such a violent world?

4 out of 5

A wonderful continuation to a scary series! This book was one of those where you think somethings a lie, and then it's the truth, and then it's a lie again, over and over untill you don't know up from down, and then you've still got to keep going.

I wasn't quiet sure where the Gladers were going when The Maze Runner ended, and I didn't believe that I could be worse than the maze and everything else they faced.

It was worse.

This book was scary in the way that makes you want to throw up, and in the mental kind of scary, the scary that mess's up your head.

And of course, this book had about the worst cliff-hanger ever written.

Of course.

So, I will be eagerly and impatently waiting for the third one. :)
