I picked this book up not knowing quite what to expect, all I knew of it was that a boy with no memory finds himself in a maze. What I wasn't expecting was a story quite as amazing as this one. Everything is vividly described, from the camp to the Grievers themselves, I found myself almost believing I was there. Thomas is a brilliant character to follow as he tries to remember why he feels like he's been there before. The Grievers, quite frankly, sound utterly disgusting and terrifying, naturally there's a lot of action and oh-my-god moments in this. It's not a pretty storyline at times, I'd recommend a readers aged fifteen plus read this but not lower. Younger reader's wouldn't understand it. An amazing, thought provoking storyline that fans of books such as Louis Sachar's Holes or Suzanne Collin's The Hunger Games will enjoy.
