Book one of the World of Tiers series. Robert Wolff blows a special horn and finds himself in another universe. In a short time his hair grows back, he loses the extra weight around his middle and he gets younger. Then the adventures begin. Kickaha the Trickster, Paul Janus Finnegan (note the initials) is the person Philip José Farmer said he wishes he could be. Farmer at his best, a lot of action and his incredible imagination.
