Excellent third book in the series. This time the war is about technology and dictators, but of course it is also a story about soldiers.
Science fiction based story about new recruits in a fighting force at the end of an empire (both the geographic end of the empire and the 'time' or final curtain call end of an empire).
The whole series (there are four books) compares favorably to the William Henry Giles Kingston books, the Three Midshipmen thru the Three Admirals and the Brotherhood of War series by WEB Griffin.
Excellent reading, that keeps you engaged and you will not want to put it down. The story includes violence (it is a war book), and alien swear words (so they don't count) and some sexual situations (which are pretty minor and nuanced).
