Eight-year-old Christopher of Butterfield, Vermont, is badly in need of a Poddley, the special creature who comes to serve lonely little boys. And Parsifal the Poddley, on his first mission shows himself to be ideally suited for Christopher. Not only does he educate him to be more thoughtful, but he takes Christopher back in time to 1659 and introduces him to Vermont in its pioneer period. Christopher participates in a conflict between the Indians and settlers and arrives home just in time to find a neighbor and friend in the person of a new little boy whose family has just moved next door. Parsifal's work over, he returns to his station, leaving behind him a nostalgic, but quite contented Christopher. Science fiction and history combine happily in this sympathetic story of boyish wish fulfillment.
