Really good book. I was afraid that it would be to childlish but it wasn't. Finally female heroine in that gengre is strong, pragmatic and not blinded by love. So it's refreshing, the world building is good enough but I would love to now more about districts. I would start reading the secomd book in the thrilogy right after finish, but it's after 3 AM and I have to get up at 6 AM...
