Artisan shoemaker and thinking man George becomes increasingly worried when the pagan forces of the Germanic tribes continue to threaten life in the Roman Empire, and he decides to risk everything for the sake of his people.
Turtledove, who has a PhD in Byzantine history, accurately portrays Christian life in the Roman Empire during the 7th century AD. Details buffs such as myself will note that from time to time he makes glaring errors such as messing up the "Trisagion prayer", but if you are not an Eastern Christian this won't bother you a bit. Also, the bishop's prayers are borderline silly at times.
One other negative aspect of the book is Turtledove's obsession with describing the status of the satyrs' sexual organs (in mythology these animals are oversexed, and Turtledove uses vivid descriptions of the satyr's erectile state to determine his mood, which gets annoying.)
The book's action moves quickly, and the author incorporates the main character George's home life quite well into the thread of the action.
I loved this book and would recommend it to those who have an interest in the genre of historical fantasy.
Now I'm not saying the book isn't enjoyable because it is but there is nothing that you read here that can't be read in any other(much better) Harry Turtledove book
However there was one part I just loved and that is why this book gets 4 stars instead of 3. I am refering to the very funny conflict resolution at the end of the story. Great way to handle that little problem!
