This is a very "dark" story. Lots of dark magic and sacrifice. Raising of the dead to a sort of "half" life. The writing is good...but interminable. Alternate history of 5th, 6th century Mediterranean and Rome's conquests. Good maps and diagrams which helped me a lot.
I have not read this book but thought I would pass it on. It is the sequel to The Shadow of Ararat. From the back cover "The Persian sorcerer has withdrwn to a hidden citadel with the remnants of the army of the King of Kings....King Maxian has raised both Julius Ceaser and Alexander the Great from the dead. Now, with the pwer that their legends can offer him, he will risk all to free Rome from the curse that protects the empire, but dooms it to stagnation. And in the east, Dwyrin's thanmaturgic unit is shatttered when Zo discovers the destruction of Palmyra. She vows revenge against the empire...."
