This book is awkwardly romantic; teen dating with adult?
This book has a long training period.
This book is "want-to-flip-page" fast book.
I thought that Divergent is very similar to The Giver. In the Giver, leaders assign 12 year old's future while Divergent has aptitude test. The Giver has long training period as well as Divergent. I think there is a lot of similar dystopian books in library.
I recommend it but it do not give any maximum in my opinion.
