Let me start out by saying that I’m not generally a huge science fiction fan. After devouring this series, I think it’s because I haven’t been reading the right writers. Here’s some back story on the universe:
Earth itself is a backwater. The bulk of humanity’s resources are in the hands of the Colonial Defense Force. Everybody knows that when you reach retirement age, you can join the CDF. They don’t want young people; they want people who carry the knowledge and skills of decades of living. You’ll be taken off Earth and never allowed to return. You’ll serve two years at the front. And if you survive, you’ll be given a generous homestead stake of your own, on one of our hard-won colony planets.
I love the world building in the series. It reminds me of Babylon 5 because each book is ultimately a story about well-rounded characters who have relationships with each other. There’s tech, but it isn’t the focus of the story. Each book gave me a lot to think about as I read.
Highly recommended for people who aren’t sure they really like sci-fi.
