The Time Warp Trio meets Marco Polo! What would happen if someone had a time-warping book he got from his uncle who was a magician, and he took it to the local YMCA pool while he played Marco? Polo! with his best friends? In the sixteenth adventure of the Time Warp Trio, it happens to Joe (and Fred and Sam). And what happens is sandstorms, desert bandits, a smelly camel, strange horoscopes, the emperor of all China, and one very famous explorer. If the explorer is Marco Polo, this must be thirteenthcentury China!
