I really love this series, so I was expecting a lot from this book. Boy, was I disappointed.
First off, although the plot was well paced, the characters were more like caricatures. They had no real depth, and certain trait were blown out of proportion. Joseph, supposedly a wise mentor, was more like a sulky, anger-prone teenager. Amos just sort of sat around and felt bad about everything. Alvec lived for nothing but sex. Belazir was just a flat stereotypical evil overlord. Ciety's only defining trait is greed.
This book is also blatantly sexist. There are very few women in it. In fact, there are only three women who show up in more than one scene. Joat is supposedly the main character, and yet throughout the entire novel, she is being constantly upstaged by Bros, who messes up her life without telling her he is to blame, who she later inexplicably falls in love with (nevermind that he's twice her age and incredibly overbearing). Joat's agency is constantly being undermined by the manipulations of the men (mostly Bros) around her, who act supposedly in her best interest.
One of the other few women of any note is Soamosa, who exists mostly just as motivation for the men around her. She spends most of the book chasing after men or weeping while she waits for a man to rescue her, while the author makes a big deal of calling her brave and modest.
Joat didn't even have a single conversation with another woman until halfway through the book when she meets Silken, who is supposedly the hard as nails second-in-command of a large smuggling ring. I had some hopes she would be interesting, but she turns out to be nothing more than the plaything of a powerful man, and she also spends a lot of time clinging to her man and weeping. See a pattern here?
As if the blatant sexism wasn't bad enough, this novel had a rushed, unsatisfying ending, and was filled with typos and grammatical issues. I'm giving it a reluctant two stars because it had the virtues of good pacing and a well-thought-out universe (even though the universe is thanks to McCaffrey, not Stirling). Overall, though, a pretty disappointing read. The rest of the series is filled with strong, interesting women, so I had expected the same from this book, too.
