I am actually very intrigued by the merpeople, and saddened that, from what I know via the Wikis, we don't seem to learn much about them and how they work at all besides the existence of "sirens" among them. After this book though, they never show up again except mentions of Jason's offscreen mermaid girlfriend Perdita until he breaks up with her for being a jealous prude (no really)
