Yes, this one was mine. (And for those who don't know, I do have some previous Champs material to my name.) And you're right, for some reason Blackwyrm don't seem to attach author names to any games books, which does strike me as a little odd. You'd have to ask them why not. Search me.
Funnily enough, my name does appear on the book's Amazon.com page, though:
