David Gerrold is an American science fiction author who started his career in 1966 while a college student by submitting an unsolicited story outline for the television series Star Trek. He was invited to submit several premises, and the one chosen by Star Trek was filmed as "The Trouble with Tribbles" and became one of the most popular episodes of the original series. Gerrold's novelette "The Martian Child" won both Hugo and Nebula awards. The Star Wolf series of novels by David Gerrold is centered on the star ship Star Wolf and its crew: Voyage of the Star Wolf (1990), The Middle of Nowhere (1995), Blood and Fire (2004), and Yesterday's Children (1972) which is actually an earlier novel that features the same main character, later significantly expanded and republished as Starhunt (1985)—it occurs prior to the other novels in the series' main continuity. The Star Wolf is a "Liberty Ship," officially designated the LS-1187. Plagued by misfortune throughout the series, without any confirmed kills to its credit, it was denied a name by Command. Gerrold had planned to develop this concept into a TV series. The later novels were written after the TV concept had been presented. The Star Wolf series reflects Gerrold's contention that, due to the distances involved, space battles would be more like submarine hunts than the dogfights usually portrayed—in most cases the ships doing battle wouldn't even be able to see each other. Gerrold referred to the concept as "World War II in space," and intended it as a stylistic opposite of Star Trek (particularly its "Next Generation" incarnation) by setting the main characters on a small, dingy spacecraft that had little respect in the fleet rather than on the flagship. Tales of the Star Wolf includes Voyage of the Star Wolf, The Middle of Nowhere, and Blood and Fire.
