In this book Katniss has struck a deal with District 13 to become the Mockingjay, the symbol for the rebels. Most of her job consists of doing propos, advertisements for the rebels to play on television throughout Panem. Katniss is reunited with Prim, her mother and Gale but many from her district are dead. Peeta is stuck in the capital and being held by President Snow in an attempt to break Katniss.
This is a very exciting book. I understand why other people like it, but truthfully it just wasn't for me. The last quarter of the book just felt like horrible violent death after horrible violent death. One of the death's particularly bothered me because it almost made me feel like the whole series was for nothing. Katniss had one goal from the very beginning and it felt like too much that she shouldn't achieve it.
I think part of my problem with this book is that it scares me. It reminds me that there are people out there that value life so little that this kind of violence is not impossible.
I did like the ending though because Katniss returns to being the person she always was. She doesn't go on to rule Panem or do anything else crazy. She settles back into obscurity and it's implied that she leads a good life.
