Aware Press, 1970, paperback. First (only) edition. One of four titles given to this publisher by Koontz that was substantially altered to the point where Koontz was indemnified against claims based on the changed material (via the Dean Koontz "Facts for Collectors" page) Very rare title. Good condition overall. Some wear/aging to covers. Spine is strong, binding is tight. Pages and text block are clean.
