I recall the author of this book interviewed with Scott Ferrall on Chivalry Today. I haven't read it but I hope to find a copy of the book in the near future!
Yep, that's what made me think of it. He's actually authored several books that are of interest to our community. I read part of "Chivalry and Violence in Medieval Europe", and it was pretty interesting. I should finish that book one of these days. That's my problem, I start books and then get distracted and don't return.
