Dor agreed to act as King of Xanth so long as Trent was gone for a week. But the weeks passed and Trent did not return. Dor knew he had to rescue his king but with no magic powers, how could it be done...?
The fourth in the long Xanth series, this is still a good read. Funny with plenty of puns and suble jokes. Fantasy gone a little wacky. I love the whole series, but the earlier ones are best.
