March to the Sea (Empire of Man II) – David Weber & John Ringo

The second installment of the Empire of Man series starts slow but gets much better towards the end. Weber's obsessive verboseness unfortunately shows up here and there. Real people just don't talk like that. There is lots of enjoyable discussion about weapons development, although a couple of drawings would have been nice for us mere mortals.

Note: This series is also known as the Prince Roger Series or the March Upcountry series.
