Parnassus on wheels is the story of a marvelous man, small in stature, wiry as a cat, yet Olympic in personality. Roger Mifflin is part pixie, part sage, part noble savage, and all God's creature. With his traveling book wagon named Parnassus, he moves through the New England countryside of 1915 on an itinerant mission of enlightenment. Mifflin's delight in books and authors (if not publishers) is infectious. With his singular philosophy and bright eyes, he comes to represent the heart and soul of the book world.
