Serpent's Reach

Serpent's Reach is a 1980 science fiction novel by American writer C. J. Cherryh. The book was nominated for the Locus Award for Best Novel in 1981. It is set in the author's Alliance-Union universe.
Specific placement of the novel within the Alliance-Union timeline is difficult because two of Cherryh's works provide contradictory dates. The events in the novel most likely begin in the year 3141 (see "Timeline issues" below). The work was first published as a Science Fiction Book Club edition through Nelson Doubleday in May 1980, followed by a DAW Books paperback edition in August of that year.
