The Gunslinger is a dark-fantasy novel by American author Stephen King. It is the first volume in the Dark Tower series. The Gunslinger was first published in 1982 as a fix-up novel, joining five short stories that had been published between 1978 and 1981. King substantially revised the novel in 2003; this version has remained in print ever since, with the subtitle RESUMPTION. The story centers Roland Deschain, the last gunslinger, who has been chasing his adversary, "the man in black," for many years. The novel fuses Western fiction with fantasy, science fiction, and horror, following Roland's trek through a vast desert and beyond in search of the man in black. Roland meets several people along his journey, including a boy named Jake, who travels with him part of the way.
