A: Unfortunately, the Counselors & Kings trilogy is officially out of print. There aren't many copies floating around, so some of the people who have them to sell are charging well over the cover price of the book.
I have a few copies of The Magehound, the first book in the trilogy, but other than that, I'm afraid I can't help you find copies. The publisher doesn't have any, and I've given away or sold all of my personal copies except for one set I'm keeping for sentimental value. Your best bet would be to check Ebay, used bookstores, and online book searches such as Abe Books.
