In language as fresh, sassy, and homespun as Huckleberry Finn's, former singer/actress Mamie Franklin recounts her last months' adventures as part-time maid and full-time psychic in Santa Monica, California. With the guidance of Ben Franklin, the 18th-century wizard whose spirit first appeared to her as a child in Mississippi, Mamie tries to cope with the death of her companion, Burley Coles, and to reconcile her son Benjie with his fatherall the while falling in love with the gifted young Theo. Slipping easily between this and the nether worlds, the wise and witty Mamie radiates a rare, irreverent joy. A fifth novel for Young, also a poet and blues musician. Charles C. Nash, Cottey Coll., Nevada, Mo.
