This was an exciting follow-up, with much more about the other factions. It's not a light-hearted read. I really struggled with remembering the details of Divergent (and got it confused with Matched and Legend), and I would've enjoyed it more if I'd just gone back and reread Divergent. Also, there are a lot of names that I couldn't keep straight - secondary characters that didn't have enough to distinguish them from each other, and thus I didn't care about their fates much. Many questions remain after the ending - it's hard to even guess what some of it means. I love the cover image.
