ISBN 0-000-00000-0 I have lots and lots of hardcover Dean Koontz books which I am parting with. If interested please contact me for information on titles and prices - the more you purchase the better price I will charge. My books are one reader only and are in excellent condition, from a Non-smoking & no pets home, clean and containing all the pages. I am selling the really large volumes for $5.00, medium size for $4.00 and smaller volumes for $3.00 each. Each book was purchased for somewhere between $20.00 to $35.00, depending where I purchased it. Some of them still have the price stickers attached. I do have some pocket books I purchased when travelling which I will sell for $2.50 each. See my photo for some titles.
