Huntress

Kira Demirci finds a new engagement for her mercenary fleet in protecting a planet against a neighbour who suddenly is more aggressive than they have ever been. The system is closer to her old home and the hand of old enemies is easily detected - and makes the whole adventure more dangerous than anticipated.
I like Glynn Stewart, he is very easy to read and I usually get interested in his characters. But this book was a bit more focussed on the tech and less on the people, so I found myself scanning whole pages quickly instead of really reading them.
