I've finished two books of the Perseverance Andrews series: The Defense of the Commonwealth and The Courage of the Commonwealth by John J. Spearman. These are both military S.F. and pretty well done at that. I think they are inspired by David Weber's Honor Harrington series. There are hints of that in this book, the main characters first name Perseverance, the government is a constitutional monarchy, the ships enter and exit star systems in a somewhat predictable way, etc. But they are not as good as those are (bear in mind I am a very big fan of the H.H. series), but they are very solid. The biggest downside I can see is that the first book The Defense of the Commonwealth starts really slowly. The author has a lot of history to bring in to set the stage for the story, and I believe that he does it in about the most Sargent Friday manner ("Just the facts, Mam, Just the facts.) that can be imagined. It was almost a DNF for me, but I "persevered." Finally, the story starts and then it is solid stuff. The second book is much better than the first. One way I think this is better than Weber's stories is that the battles are far less one sided and the losses in each battle are considerable which makes the bravery involved in fighting them both more chilling and perhaps a bit less realistic? I've never been a soldier so I'm not sure what it takes to go into a battle and understand that your chances of surviving are very low. I find time of the battles, which are almost always less than a minute long, to be more realistic than Weber's long drawn out battles. Sigh! but they are a bit less fun because of that. --- Should space battles be fun? That's a question worth considering.
I have the third, and so far the last one; The Resolve of the Commonwealth queued up and ready to roll.
