I have been following Jack Campbell’s Lost Fleet Series since about 2006. Lost fleet is coming to an end next month and a new begining in a new series Lost Fleet: Beyond the Frontier. He also have a contract for another series in the same universe called Phoenix Stars.
Now I want to check out the other material he has written, there is a JAG in space series, Paul Sinclair and Stark’s War about a professional soldier.
He writes pretty straight forward enjoyable military science fiction with better than average characterization.
