Call it "speculative history" or "active history", this novel is based on the idea that the South wins at Gettysburg, and what could have followed such an event.
This book attempts to be faithful to historical events insofar as real people from the Civil War are given roles that are as consistent with their real characters as possible. For instance, Union General Dan Sickles is a self-aggrandizing egotist who very well could bring about the disasters of this story. They are also slaves to the same weather and other real-time conditions that prevailed at that time.
Best of all, this book is fast paced and engrossing as the authors create a Civil War story in which you don't actually know the ending. Unfortunately for me, that will not be so when I finally get book one of this series, Gettysburg. But I will get it! If it's as entertaining and fun as this one was, I won't mind at all. This is a 4 star story!
