Overall it is an interesting read. However, there was a section through the middle of the book that was basically useless drivel. Unnecessary details about various plot lines that are never followed up on and don't add anything to the real story in my opinion. The author goes to extreme lengths to display the characters from the 1940's as shallow bigots and the characters from the future as paragons of multiculturalism. Which is fine to a point but quickly gets tiresome as this theme gets hammered on over and over again. My final analysis is that it is a fairly well written and interesting story that could have been pared down a bit.
Liked this book enough to order the two remaining books in the trilogy. Definitely a good military genre read.
