Mockingjay (Hunger Games #3) by Suzanne Collins
In this last book of the Hunger Games trilogy, everything comes flying apart. The book feels like a spiraling descent into chaos and madness, but it's done oh so skillfully. You can feel the danger, fear, pain, and loss of sanity. This is a world that is cruel with the sing-song nature of an insane child murderer.
I would say that this book really deserves a "This shit is not for kids" sticker. I'm not even sure it is at all appropriate for young adults much more so than even the previous two books.
I had a minor issues with Gale. In the previous books we really don't see much of Gale because he's not a contestant. Now that there are no more games, he can play a more prominent role, but I'm not sure the way his character turned out gels well with how he was portrayed previously. This may be because I missed out on characterization cues before or perhaps because there just wasn't enough room to give him much depth, but I just don't feel like Gale was really Gale.
All that being said, it was still an excellent book and a fitting ending for a powerful trilogy.
