It's Young Adult, if that sort of thing matters to you. But it's not bubblegummy or trite. I also really enjoyed the fact that it was set in Hawaii, a location that I don't think I've ever experienced in a novel before. And seeing as I didn't know much about the islands before this, I actually learned a lot about the location.
The tension in the book was also particularly good. Kept pulling me back in but wasn't so strong that it exhausted me emotionally. Good main characters. Smart discussion of what it means to be an outsider. (The main character is half white/half islander.)Very much enjoyed it.
