Ok, I think I just wasn't in the right mindset to read this book and it rubbed me the wrong way because of it. First, I didn't read it immediately after reading the first two, and I think that hurt me because I'd forgotten pieces of the storyline that I then had to recall, and while I was usually sufficiently reminded of them at some point, it wasn't as soon as I wanted it to be sometimes. That's my own fault. But because of that, I think it made me feel worse about the story than I might have felt if I'd read them back-to-back. Can't be helped at this point. I just did NOT like the dynamic between Matt and Evan at the beginning of the book. Evan seemed to be almost back to square 1. Yeah, he did get there, and it was OK in the end. I just felt like too many things were touched on but not expanded on enough, like "here's a problem-ooh, solved-and here's another-wait, that's solved too-what about this problem..." and things just fell back into place too easily. Evan did change over the course of the story, but something just felt off, and I don't know if it was me or the story, so I'm giving the story the benefit of the doubt. 
 So, if I were rating based on what I felt upon finishing, it'd probably be 2 or 2.5 stars. Given that I think I might have felt differently had I read the books closer together, I'm giving it at least 3 for now. Maybe I'll re-read some day and feel differently.
