Louis L'Amour's Lost Treasures is a project created to release some of the author's more unconventional manuscripts from the family archives.

Matt Bardoul was a good man to have as a friend and a bad one to make trouble with. He was also a single-minded drifter-until he met his match in an outspoken beauty named Jacquine Coyle. She was headed into the Bighorn Mountains with her father and an expedition in search of gold. After Matt signs on to join them, he discovers that there is a group of outlaws in the party-gunfighters and thieves that Matt wouldn't trust for a minute. At first it's unclear what they are planning, but before long Matt realizes that he's the only man standing between innocent people and a brutal conspiracy of greed, lust, and cold-blooded murder.

In Louis L'Amour's Lost Treasures: Volumes 1 and 2, Beau L'Amour takes the reader on a guided tour through many of the finished and unfinished short stories, novels, and treatments that his father was never able to publish during his lifetime. L'Amour's never-before-seen first novel, No Traveller Returns, faithfully completed for this program, is a voyage into danger and violence on the high seas.

Additionally, many beloved classics are being rereleased with an exclusive Lost Treasures postscript featuring previously unpublished material, including outlines, plot notes, and alternate drafts. These postscripts tell the story behind the stories that millions of readers have come to know and cherish.
