When Flare O'Flaherty-son of Ireland, mountain trapper, and gambler-agrees to lead a group of missionaries downriver to the remote headquarters of the mighty Hudson's Bay Company, he doesn't expect to face the greatest challenge of a wandering man's lifetime in the form of the Snake River.

Accompanied by Margaret Jewell and Shoshone Sima, Flare searches for his destiny along the mighty river that bears the shape of a serpent-and holds the promise of home.

An adventurer's story told like never before, the Rivers of the West saga follows those compelled by the evocative grasp of the untamed frontier, looking to carve out a place in America's most awe-inspiring backcountry.
