I'm holding off on a rating for this, as I feel like I didn't appreciate it the way I should have. Not sure if it was because I've been reading a lot lately or what, but I had a lot of trouble getting into the book. The story was fine, the plot was fine, the writing was fine, but for some reason it just didn't grab me and I ended up just reading it bit by bit. If I tried to read big chunks of it at a time, I'd start skimming and forgetting what I'd just read. Really not sure why I couldn't get into it. That said, there were things I enjoyed about it. 
 I very rarely read YA with a male narrator, so that was a nice change of pace. And it's definitely a neat idea to have a story about merpeople from a male perspective! Most of the teenagers seemed pretty realistic in terms of attitudes, actions, and dialogue.
