Wizard Ho , the seventh and last novel in the Columbiad series, follows a merry band of Mahattanites in their search for a Wizard and his sidekick, Ripple, who operate a clandestine radio station that represents the embattled voice of the twentieth century intent on identifying the American soul. An interacial couple, Jim and Columbia Ruth, inspires a parade of dancers, musicians, videographers, writers and film buffs to find these radio mavericks.
