Jon Sharpe is the pen name used by a number of different authors who wrote a series of western novels titled "The Trailsman." The series features the adventures of the protagonist Skye Fargo, who traverses the American West. Because the "Jon Sharpe" moniker has been employed by various ghostwriters, the actual identities of these authors largely remain unknown to the public. This pseudonym approach allows the series to be written continuously and prolifically, with over 300 books published since its inception in the early 1980s. The Trailsman series is known for its action-packed narratives and is a long-standing staple of the western genre in popular fiction.
