The Old Gods Waken by Manly Wade WellmanRead about the other entries on the list.
Wellman’s Silver John is a kind of country-folk Dr. Strange or John Constantine. Armed with a silver-stringed guitar and a wealth of folksy know-how, John the Balladeer wandered the Appalachian mountains of North Carolina, facing druids, ancient deities, and black magic. The Old Gods Waken is the first of the Silver John novels, and it is heavy with country-folk hoodoo and Native American folklore. This is a story that shows how the old world and ancient traditions impact the “modern” backwoods world.
