Katniss wakes up in District 13 (yes there is still a District 13 which is being run by President Coin), she later learns of the destruction of her very own District 12. Thanks to Gale - her mom, Prim and a very few others were saved. On the downside (and of course this made me worry), Peeta was captured and is now in the clutches of the evil President Snow.
As we know Katniss is the Mockingjay, the symbol of hope and since most of the disctricts have started a war against the Capitol, she must take a stand and be their guiding light. Peeta on the other hand was brainwashed, so the moment he saw Katniss, the first thing he did was strangle her - that did not go well.
I really liked how the book ended because as I said, I am for team Peeta. Mockingjay was a slow read compared to the first two novels as it went on about the uprising, we also see Gale to be more of the supporting role - the goodlooking rebel who will not get the girl. My one wish is that Cinna was alive. Remember on the first book where he said that he chose District 12? It would have been great for him to elaborate on that especially being someone who was born in the Capitol, also because he is such an interesting character.
Overall, I am truly satisfied with how it ended especially because Peeta & Katniss will live happily ever after (although they will always be scarred by what happened) with their 2 children. I truly reccomend this trilogy and look forward to the movie in 2012.
