I don't think I can rate this with a clear conscience, since I read the first fifty pages and the last twenty-five. The concept was absolutely fascinating (and a direct homage to Lord of the Flies), but it was so over-the-top that I couldn't get into it. I do still love Libba Bray, though, and her Gemma Doyle trilogy is one of my most favorite YA series. I'd recommend reading those instead.
