Look, this isn't a perfect book. Let's be honest, but the one thing that Armstrong did in this series (and sadly it still stands out today) is she actually has the women interact with each other. The bad guys are men and women, and the good guys are men and women. The evil women work together and the good women work together. The women are not in competition with each other and are actually friends. Even today, this is somewhat rare in UF and it is so refreshing to see this.
Additionally, in this book Armstrong shows how being a good person who has had a stable life does not necessary equal boring. I like that.
