Third book I read of this author, this time it was because my mom bought me this book as a present when she went on vacations, otherwise I'm sure that I would have read it but not anytime soon.
I will repeat what I always say of his books, while the ideas of his books are original, they still look (to me) a little superficial, without much developed plot and, a little commercial, ie written to sell.
I will not deny that this works because I enjoyed the book, the transition is fast paced but constant from beginning to end. And, again, the secondary characters steal the spotlight more than once and I ended up preferring them rather than the protagonists.
The ending is bittersweet, typical of Green, but in this case that's is something I see good, I liked it ended that way.
