Tor Doubles: #0: Keith Laumer’s The Other Sky and The House in November

The House in November cover by Mike Embden
Between October and December of 1969, Keith Laumer’s novella The Seeds of Gonyl were published as a serial in the magazine Worlds of If. The story was published the following year in a hardcover by G.P. Putnam & Sons under the title The House in November, and in 1971 as a paperback by Berkley Medallion.
In 1981, Tor reprinted the novel as part of its “Jim Baen Presents” series, but, apparently deeming the novel too short, it paired it with Laumer’s story “The Further Sky,” which had originally be published in the December 1964 issue of Amazing Stories. That story had also undergone a name change and appeared as “The Other Sky” in various reprints, including its appearance with The House in November.
When Tor Books reprinted the volume in 1985, they included a shield on the cover identifying the book as a “Tor Double.” This book may possibly have been created as a dry run or proof of concept for the eventual Tor Double line. The cover for The Other Sky was provided by Thomas Kidd and the cover for The House in November was provided by Mike Embden, although their credits are reversed on the copyright pages.
