110?! Yikes, yes, I can see why you might have a problem locating that many. You might try used bookstores--the major one in my area often has KK's titles in stock--but usually they only have two or three copies of the same title in at the most, not large quantities. I don't think it's available yet in ebook or audiobook either, although some of the other titles (the King Kelson era ones) are. Maybe that might be a solution, if you'd be willing to switch to Deryni Rising or one of the other books in that time period? Or the books in the new Childe Morgan series are definitely still in print.
