If Robert E. Howard had been writing his historical adventure fiction at the beginning of the 21st century instead of toward the beginning of the 20th, this book might very well have come from his pen. I'd highly recommend this to anyone who enjoyed the Howard collection "Sword Woman."
Still, while I'm recommending it, it's not without its flaws - some of those the same as I feel the Howard stories contain. The narrative can get bogged down in technical details that impede the flow of the tale, and the characterization is fairly basic. The 'big reveal' here is also pretty obvious right from the beginning.
This is a fun little book, but it's really not in the same category as 'Yiddish Policeman' or 'Kavalier & Clay."
