The merpeople really do sound interesting. But even in this book, we only learn about them as they pertain to Anita's sex life.

Poly people sometimes get a bad rap; many people think they're critical of monogamous people, the way many monogamous people are critical of them, when most of them aren't. LKH, however, is. Though with her, I think it's not so much that she's poly. Rather, she hates other women and thinks she (or at least her self-insert) is entitled to every man's penis.
