Verdict: Action packed, just don't overthink it!
#1 - The Maze Runner
#3 - The Death Cure
This series is very readable, even though it doesn't give a lot of answers or make a lot of sense. The chapters are short, most ending on a slight twist or revelation, and there's plenty of action, drama, and danger. The characters also come out of their shells a bit more, and the true world starts to rears it's scorched head, constantly throwing new challenges in Thomas' way.
I had the same issues with this book as the last. Thomas's journey is very entertaining, but the answers are loose tie ins that will fall to bits if you pull at them. It just doesn't make a lot of sense if you think about it (I'm being vague here to avoid spoilers). The action, twists, and horrors come first - the explanations are not as important, or so it would seem. As long as you can get to grips with that, there's a great book to enjoy in this.
With all that has happened, I feel like I have even more questions now than I did after book one. If book three pulls through with some answers, this will be a great series. There are some great mysteries in this, as long as there are fitting answers, and I'm not entirely sure if Dashner has them. It really does depend on what all these trials really mean...
