Derek Calver touches down on Lorn and is determined to
join the Rim Runners to explore desolate planets.
He joins the crew of Lorn Lady and sets forth for Mellise, inhabited by
intelligent amphibians; for Groller, where the natives have just qualified
as humanoids; for Stree with its tea loving lizards; and Tharn, home of
a pre-industrial civilization.
The Avalon edition is dedicated "To Susan, who belongs on the Rim". The other editions are dedicated "For Susan, whose blend of saintliness and cynicism is peculiar to the Rim."
Two chapters (4 and 5) included in the original Avalon edition of this story have been removed from the subsequent Ace and Priory editions. These chapters are included in the CD ROM edition.
"A long time ago the first of the Rim Worlds novels, The Rim of Space (my title was To Run The Rim) was published in hard cover by Avalon. Very shortly thereafter it was published, in paperback, by Ace. In those days Ace had a limit of 40,000 words. The book was episodic, so Ace merely excised one chapter without any effect upon continuity. Unluckily the artist responsible for the Ace cover read the book in hard cover before doing his pretty painting. And, of course, he just had to illustrate the hacked—out chapter."
