This book had me on an emotional rollercoaster toward the end, but the rest of the book was a little more subdued than the previous one in terms of action, and the emotions were different, more toward the hopeful and positive side. But I was still just as invested in the characters and just as hooked wanting to know how things were going to play out.

This book, much like the others, continued to make me think about the concept of humanity (all that stuff I talked about in my review of Book 2 and a little in my review of Book 1), but this one, in a way, brought things full circle, just as Eve said. However, even when it brought things full circle and they did something good, it still wasn’t exactly cut and dry, and it left me pondering things even more. Were the main characters really any better than the scientists? Or rather, were the scientists really any worse people than the main characters? Was anyone really to blame for what happened to the world? Was everyone to blame? Do intentions make a difference, or is it only the outcome that matters?

In the end, all the loose ends were tied up, and this book brought a satisfying conclusion to a series full of realistic, likeable characters, emotional situations, and thought-provoking depth that I’m really glad I read!
