Don't know if anyone else here is a fan - but I waited about 10 years for him to come out with a new book and just this weekend found out that he did come out with a new book (2-book series, actually) in 2002! I spent months going into the book stores looking for new stuff by him, so it must have come out after we moved...
Anyway - I'm estatic! Got it at Forbidden Planet on Shaftesbury Avenue - where they also have Chelsea Quinn Yarbro books (love her, too) and probably more than a few others I've had a hard time finding here in the UK.
