I've sat on this review for two days now. 
 I loved this series but I feel like Ness may have pushed it too far with this book. 
 The first book was told solely by Todd. The second book was told by both Todd and Viola. Ness made a smooth transition between one story teller and the other, making sure that the best part of the story was told by the best person. 
 Both books made fantastic endings. The cliffhanger fantasticness that books 1 and 2 had had me raving about these books. 
 But I feel like Ness took his cliffhanger superpower and used it for evil with this last book. Every other page, sometimes twice a page, every time Ness switched storytellers, he made it some grand cliffhanger. 
 I loved the introduction of the third storyteller, at first I wasn't sure as I didn't like the use of another text, much less a comica style text which does NOT fit the character or the story at all, but after the initial storytelling I warmed up to said narrator. 
 Overlooking all of this and skipping to the ending. I felt it was very fitting for a teen lit. I wanted it to end differently, and thought that it ended in a very fitting way, but then the surprise ending was a bit lackluster. 
 Ending spoiler: 
 (view spoiler)[ I felt that Todd killing the Mayer would have been very fitting, but the author felt the need to keep him pure and unkilling. Using a spiel about Todd becoming like Ben instead of the murder of the Mayor pushing him toward becoming the Mayor. 
 I was able to look over that and then thought Todd was dead. Bittersweet, but a doeable ending, one that I would have been ok with. But bringing Todd back to life really just felt childish and like the author was trying to shield young readers from what could have happened. I get it, children's literature rarely has the main character die (can I use never, bc I think it's never but I'll cover my bases and say rarely.) but it would have been befitting that TOdd gave it all for this new world and Viola could have lead with Lee, whom was never truly given enough credit. (hide spoiler)] 
 Overall, a very good series. I loved the first two and if you like multiple narrators (which I still do not!) then you will like book three. If you hate it, you will still, at the end, enjoy the story, you'll just be annoyed the entire time you're reading it.
