Brothers of Earth is a 1976 science fiction novel by American writer C. J. Cherryh. It was the second of Cherryh's novels to be published, appearing after Gate of Ivrel, although she had completed and submitted Brothers of Earth first. Donald A. Wollheim, the editor of DAW Books, decided that publishing Gate of Ivrel first would be more commercially desirable, so Brothers of Earth was delayed until the former was released. The book was first published as a hardcover Science Fiction Book Club edition in June, 1976 and followed by the first DAW paperback edition in October of that year. In 2003, DAW re-released the book in an omnibus edition along with Cherryh's 1977 novel Hunter of Worlds. The omnibus edition was entitled At the Edge of Space. As with Gate of Ivrel and its sequels, Brothers of Earth is set in Cherryh's Alliance-Union universe; however, these novels describe events distant from and largely unrelated to her many subsequent works in that timeline. The book was ranked 10th on the 1977 Locus Award for Best Novel. Source: Wikipedia (en)
