Yondering is a collection of short stories by American author Louis L'Amour, published in 1980.
 A departure from L'Amour's traditional subject matter of the Old West, "Yondering" contains a mix of adventure stories and character studies, primarily set in the first half of the 20th century.
 Two of them are set during the World War II era, with many of the stories drawing upon the author's own life experiences.
 The book's publication celebrated the milestone of L'Amour having an estimated 100 million books in print at that time of publication.
Hondo is a 1953 Warnercolor 3D Western film directed by John Farrow and starring John Wayne and Geraldine Page.
 The screenplay is based on the July 5, 1952 Collier's short story "The Gift of Cochise" by Louis L'Amour.
 The book "Hondo" was a novelization of the film also written by L'Amour, and published by Gold Medal Books in 1953.
 The supporting cast features Ward Bond, James Arness and Leo Gordon.
Haunted Mesa is a science fiction novel by Louis L'Amour, set in the American Southwest amidst the ruins of the Anasazi.
 L'Amour attempts, as in others of his works, to suggest a reasonable explanation for the phenomena attributed to The Bermuda Triangle, i.e., portals between worlds or different facets of this world.
 The same phenomenon is used, albeit in a very minor way, in his novel "The Californios."
 A useful contrast between the two novels is that in "The Haunted Mesa," the Anasazi leadership, who rule both the portals and their people with an iron hand (the Hand and the Voice are two of the leaders), are corrupt and thoroughly evil, whereas the person or people who know about the portal in "The Californios" are reserved and rather helpful to people they respect.
 These were different portals however, and did not necessarily lead to the same location.
Last of the Breed, a 1987 book by Louis L'Amour, tells the fictional story of Native American United States Air Force pilot Major Joseph Makatozi (Joe Mack), shot down by the Soviets over the ocean between Russia and Alaska and then captured.

 It was L'Amour's second-to-last published novel.
Percival Christopher Wren (1 November 187522 November 1941) was an English writer, mostly of adventure fiction.

 This was one of 33 novels and short story collections that he wrote, mostly dealing with colonial soldiering in Africa.
Kipling Morgan, better known as Kip Morgan was a fictional character created by the bestselling author Louis L'Amour.
 Morgan is a detective, like the hard-boiled detective characters created by Dashiell Hammett and Raymond Chandler.
 In L'Amour's words, "Kip Morgan is an ex-prizefighter struggling to make a new career himself as a private operator."
 L'Amour wrote a few short stories featuring Morgan including "Dead Man's Trail", "With Death in His Corner" and "The Street of Lost Corpses".
 Several of the stories make up the latter third of Vol.
