Spoilers annoy me; I avoid them like the plague. Sometimes you get blindsided by them, though. I heard a few of the most gut-wrenching details from Suzanne Collins's final Hunger Games novel, MockingJay before I managed to read it, which sucked out some of the impact the book had on me.
Still, I really enjoyed it. The end fulfilled the potential the series had built up. It had a certain exhausted poignancy about it. The brilliant character development begun in the first two novels carried through to a nice conclusion, the tone of setting changed without losing the tone of the first or second novels, and all in all, Collins rocked it, and like any truly empathetic story, readers either love or hate how it all turned out. Either way, passion is assured, whether they feel the final chapters of worthy their dedication or a betrayal thereof.
If you are one of the few book people not to hear of and/or read this book already, or are a non-book person who reads a book a year, I say you get your hands on the full series, including BUYING Mockingjay. It's earned a re-read, whether you're a "young adult" or not.
