The one problem with all of his hardcore stuff is that usually the small prints sell out of his books, fast. My friend picked this book up on ebay for an obscene price... and take in mind the price of the book is 45 bucks (for the hardcover, at least.)
I've been warned to stay away from his Leisure fiction stuff, but I'm definitely interested in checking out some more stuff. I've got 3 more of his books to get through now.... hopefully they'll be as good as this one.
(edit- hardcover, not hardcore)
