I gave this book 4 stars because it had a great premise & was a very engaging read. It only took me about 3 hours to read it because once I got past the first chapter or so I was fully engrossed. The main character's actions frustrated me quite a few times throughout the book, he didn't do certain things in what I felt were a common sense way & I was frustrated by that. I did like the final resolution but I don't know how to feel about the very, very end... No spoilers though. I'm just unsure if it was needed, or should've ended before that last little detail. I think it would've been a little better without it.
