The Jericho River: A Novel About the History of Western Civilization is a novel from David W. Tollen that’s won a whole bunch of awards (London Book Festival, Next Generation Indie Book Awards, et al) and which should appeal to RPG fans.
The novel sets about presenting history as an adventure story. The Jericho River runs through a world shaped by myth and history. In this adventure Jason Gallo sails along it in search of his estranged father, battling pirates and monsters on the way.
The river flows like a timeline, carrying Jason along in chronological order and so traces the history of Western Civilization. The notes at the bottom of the page are from Jason’s father, Professor Gallo, and shed light on characters like King Arthur, the origins of Snow White, coffee and even the Internet.
