Today alphacygni and I spent a nice afternoon at the Bookmill. I picked up a paperback copy of The Brewmaster's Table, which is a book that I've been saying for at least a year that I'm surprised I don't already own. After I got home, though, I thought the book looked odd, and indeed, they've changed the cover from the hardback to the paperback.
I know that there are lots of reasons to change the cover of a book. I really hope that one of the reasons was not "The book will sell better without a black man on the cover".
