2.5 stars. 
 Thomas is dumb. He drove me nuts the entire time. James Dashner what did you do to Teresa? Why? Seriously. And who the hell is Brenda? 
 Thomas apparently has "great" instincts. He seems to know instinctively who's good, who's bad, and when a situation is good or bad. All. The. Time. But when you have nothing else going for your character, I suppose it is okay? 
 All the backstabbing and double crossing... what the heck is going on? I was confused to the point that I really don't care who is working for whom anymore. Group B was there to... what? Capture Thomas so Teresa could betray him? Yay. Whatever. I don't care anymore. 
 And Teresa and Aris? What the? I really liked Teresa but now I just don't know. She claims she did it to make sure Thomas lived, and I can support that, but I'm just not sure. 
 And Brenda? Who are you and where did you come from? I am with Teresa here, and hate your guts. 
 Newt and Minho... you guys are cool. I loved your rescue of Thomas. 
 Overall, I was bored by this book. I had a like/meh relationship with it. Sometimes I liked it, other times I wondered why I was even reading it. But over all I guess I liked it enough to continue and see how it all plays out.
