I would say this is a three-star book that got four stars because I couldn't put it down. I read it every night until my eyes were closed and I had to open them to turn out the light. I liked that Saldin took a low-stakes plot (not a murder or a war, just some teenagers at camp) and made it into such a powerful story. I also found it rang with truth. I wonder if everyone who loved it also had to choose, at one point, between being a good friend to someone who could probably use it and being enthralled to someone who probably isn't going to treat you well in the end. I don't think I have ever read a book with this dynamic as its theme, and now I wonder, why not? Recommended.
