In this final book of Maze Runner everything comes together. I was reluctant to finish the series after reading the first book, because I've read somewhere that Teresa dies and I quite liked her in first one. But upon finishing all three it all kind of makes sense. I liked the ending. I wasn't typical "all is well" end, but it rather made sense for this world... in a way. Even Teresa's death. 
 I like story, all books combined. I also liked, that the story wasn't dragged out (like in some books, where you know, that story could end in first book if just added 50 pages). In the end it all made sense. 
 For the bad part, I still want for Thomas to get his memories back. I mean, I understand why he refused, but still. It would be nice if there more character description, at least appearance. And maybe a bit more romantic development, especially in the middle part. 
 But all in all great book and great series.
