Oh man, I'm still in pain, trying to assimilate what happened to GS. I guess the only way to take that out of my mind, will be when James Dashner publish a new book.
This was a fantastic book, and power of synthesis was made clear, since despite being shorter than what's frequent, A LOT of things happened!
Plus, I love how disconcerting is reading Dashner's turns of events, almost as much as his endings. When you think you know everything, he makes you realize that oops, you got it all wrong, actually!
