I really love the central idea of this book. It’s a very creative concept that deserves better treatment. Before moving on to my main issue, the author deserves criticism for building a world where the main character — a man — owns a large group of women as slaves. (Some men, but they barely figure in the story and only two or three get names.) He genuinely does not mistreat them, and even treats then more or less as equals, but they are nonetheless slaves to the end of the book.
My central issue is the overall lack of character development. The main character and maybe two others show some richness over the course of the story, but everybody else comes across as highly two dimensional. Even that might be forgivable if there were a villain. Technically, there are villains, but they remain faceless and nameless to the end. We don’t learn why they wanted to kill Felix Campbell. We don’t care that they are gone. There is no big reveal that it was that one guy all along. There are guns and bombs, but you never learn why anybody is pulling the trigger.
