The book takes an unexpected -by me at least- turn compared to the first two in the series. 
 Katniss and Peeta are no longer in the arena but -in the first part of the book- separated and they're back together it's not like it was before. 
 This was quite an emotional read for me because Collins isn't afraid to take some risks. 
 No vampire babies here, but characters that have suffered so much they're not sure they can take it anymore. The effects of war are so immense and lasting that people barely even dare to hope at something better. 
 It may not be perfect but I think it's a superb achievement by Collins. 
 So stop whining about the whole Peeta/Gale thing!
