This new one is called Leaders and like the previous a rare read.
It's not often that I read SF novels. The main reason is that I don't want to copy anyone, and unlike most of my own, full of wormholes and exploding - well everything, this novel is more sedate but no less interesting because of it. It's one of those superior novels that makes you want to keep reading, to keep turning the pages to find out what will happen next. Interbreeding with other races by starship voyagers is an unusual concept but Karen's style and skill makes it seem not only real but probable. Her construction of different races and cultures is effortless. All in all a terrific novel filled with myriad interwoven themes and sub plots. I would recommend it to everyone.
