That book sounds fascinating! I don't know how I'd missed hearing about it unless it's because its publisher, New South Books, is a good small press that lacks the publicity machine that larger houses have.
I looked the book up, and for anyone else who's wondering about it, it's called "Unmasking the Klansman." Thanks a million for telling me about. I'd bet Carter will do a signing at our local indie, and I'll certainly watch for it. Here's some info for others who also haven't heard about it:
