Star Bridge

Blurb

Star Bridge is a science fiction novel by authors Jack Williamson and James E. Gunn. It was published in 1955 by Gnome Press in an edition of 5,000 copies. However, 900 copies were never bound. It was also issued in paperback by Ace and reissued by Berkley Books in 1977 and by Ballantine Books in 1982.
Williamson initially wrote about 50 pages in manuscript for the first draft, and worked up about 150 pages of notes for the novel's completion. Finding himself "blocked" on the project, he turned his materials over to Gunn, who completed the book. It was sold to Gnome for a $500 advance.
It is an adventure story in the classic Williamson tradition, woven with a reflection about the relative importance of impersonal forces and individuals in the events of history.
