More like 3 1/2 stars, I think. 
 This was an odd read for me. I was captivated by the plot, but not the writing style. I've seen several reviews here by others that talk about Dashner's tendency to tell instead of show. I'd have to say I agree with that. Further, I'd also have to say that this was the strangest limited omniscient narrator I've read. 
 It's clear it was meant to follow Thomas, but at the same time, it still leaves holes. (view spoiler)[After he deliberatly is stung by the Grievers, he has memories--but we have to hear about them piecemeal as he tells others, although he clearly remembers the experience. This approach would have been better suited had the tale been told from Newt's perspective instead. Then the holes in the story would have been justified. (hide spoiler)] As it was, there were places where he pulled back the narrator's access when he just didn't want the reader to know something. Inconsistencies like these bother me. 
 I was also disappointed (as others have been) at Teresa's lack of power as the only female lead. Thomas alludes to her strength and her ability to beat out over half the Gladers, but we never see any proof of that. In fact, she's pretty well sidelined and inactive for very much of the time. She could have been so much more powerful. 
 That being said, I still thought the story's premise was solid--just stylistically disappointing. Will I read The Scorch Trials? Probably, if I can get my hands on it. 
 Bottom line: Fans of The Hunger Games (for whom some have recommended this book) will likely find it tepid and remote stylistically. I was broken hearted to lose Rue; not so much so to finish this book.
