David Weber and John Ringo’s* Empire of Man military science fiction series was great fun: if you’ve never read it, Empire of Man (Books 1 & 2) and Throne of Stars (Books 3 & 4) have been collected for your amusement. Worth your time to peruse, if you haven’t. Although I imagine that Weber / Ringo fans are not exactly under-represented among my own readers…
*I originally wrote that as ‘David Ringo.’ Which is not a slam, I swear.
