I picked this up a couple months ago, thinking it sounded good, but no real rush to read. I was, in fact a little bit leery of the high school world. However, it just pulled me in! By the end, I was just dying to know what they really were and more of the history between the characters. The characters were also quite interesting, and believable. I will definitely be continuing this series, and am quite interested in Riley's spin-off story, as well.
