Just finished reading the Lost Fleet series from Jack Campbell and really enjoyed them.
I also recommend John Ringo's Aldenata Universe books if you like military scifi:
A Hymn Before Battle
Gust Front
When the Devil Dances
Hell's Faire
And with Tom Kratman:
Watch on the Rhine
Yellow Eyes
The Empire of Man series with David Weber is also great reading:
March Upcountry
March to the Sea
March to the Stars
We Few
The Council Wars series is also very good:
There will be Dragons
Emerald Sea
Against the Tide
East of the Sun, West of the Moon
I actually have all these in pbook form, and now also in ebook form from the
