*This review is for both The Ask and the Answer and Monsters of Men* 
 In short: The Ask and the Answer and Monsters of Men by Patrick Ness are emotionally taxing reads, but the payoff is so worth it - beautifully written, tremendously complex in plot, and powerfully inspiring in message. 
 I've decided to combine my reviews for the second and third book in the Chaos Walking Trilogy (The Ask and the Answer and Monsters of Men) because I realized there was so little I could tell you without revealing some major aspects of the plot. If that isn't a testament to how dynamic and surprising the plot of these final two books is, than I don't know what is. 
 One of the most fascinating aspects of The Ask and the Answer and Monsters of Men is the introduction of some very complex politics and character dynamics. A Mockingjay-esque situation is introduced in which there are two power-hungry leaders on opposing sides, one of them acting under the guise of the "good guy". The character complexities are so well done that in the span of chapters, I would change my mind about the alleged goodness and badness of these characters and then back again. Who is the relative good guy in this situation? Who is really telling the truth? Who should Todd trust? 
 The Ask and the Answer and Monsters of Men take a decidedly darker turn in the story (and anyone who's read The Knife of Never Letting Go knows that it wasn't exactly a light read either). War, genocide, and torture are major themes in these last two books making for a heavy, emotional read. It took me quite a long to make it through them - not only because of the mammoth page numbers - but also because of the depth of the subject matter. 
 Ultimately though, despite the seemingly helpless situation, there is one thing that is always present in The Ask and the Answer and Monsters of Men that keeps you reading - hope. It would've been difficult to make it through these books without the promise of a happy ending. There was hope that peace would win out in the end. There was hope in one of the most inspiring and powerful romances I have ever read. And there was hope that Todd would never completely compromise his morality in situations when almost every other character did. He is, after all, The Boy Who Can't Kill.
