Notes: Info based on a listing in Locus #218 (January 1979), but there is no evidence that this book was ever published. The Dell paperback published in 1981 has a 1981 copyright (so does the Baen paperback published in 1988). There is no OCLC record of a hardcover edition and nothing for this ISBN. There are no copies of any hardcover edition for sale by Abebooks.com dealers. The ISBN shown in the Locus listing doesn't even belong to Dutton. It has the Arbor House prefix. Therefore, the date of this has been changed to 8888 (unpublished) and the title record's date has been changed to October 1981, the date of the Dell paperback printings.
