This felt to me like a toned down version of grasshopper jungle, with worse writing. Some parts of this book were just soooo cliche, and cheesy. But there were other parts that were unique, and heartfelt. It kept me interested the whole time, and my reading experience was wonderful. Sometimes the author would bring up points that didn't add to the story(if your going to mention a shot gun it better go off in the next chapter, and all of that.) Like with Diego for example there were some odd tensions between him and his sister that were never explained, and I was kind of annoyed by their on and off relationship. There was just a lot of side plots that were kind of the main plot but not really. The whole thing was barely held together. 
 Anyway this review was all over the place, but one last point. SPOILS I like books to have somewhat of a nice wrap up at the end. Whats up with the whole "it doesn't matter whether the world ends bullshit" like I want to know whether the sluggers brought him up one last time, or nothing happens, and he was actually fucking crazy. Anything really. Especially because the ENTIRE book was leading up to a very specific date in time.
