My personal opinion is that this is a very well done alternate history version of the battle of Gettysburg. Some folks here tend to disagree with this book in general if you look over some of the reviews. Perhaps that would have something to do with politics, maybe some disagreement with the author. I say do not overlook this book just because perhaps you may disagree with Mr. Gingrich. This is the first in a series of books that I look forward to reading more of. For anyone looking for a very interesting look at what could have happened if a few different decisions were made, and how those would effect the outcome of history, I say this is a very good book choice.
