Crossover Covers: The Merkabah Rider series by Edward M. Erdelac

Edward M. Erdelac is the author of an excellent series of four books (three collections and a novel) about the Merkabah Rider, a Jewish mystic gunslinger battling the Great Old Ones in the Old West. Besides the strong ties to the Cthulhu Mythos, a number of other works of fiction are referenced, and therefore I will be including this series in the new volumes. Highly recommended.
