The Elfin Ship Publisher's Summary
Trading with the elves used to be so simple. Every year Master Cheeser Jonathan Bing would send his very best cheeses downriver to traders who would eventually return with Elfin wonders for the people of Twombly Town. But no more.
First the trading post at Willowood Station was mysteriously destroyed. Then a magical elfin airship began making forays overhead; Jonathan knew something was definitely amiss. So he set off downriver to deliver the cheeses himself, accompanied by the amazing Professor Wurzle, the irrepressible Dooly, and his faithful dog Ahab.
It would have been a pleasant trip, if not for the weeping skeleton, mad goblins, magic coins, an evil dwarf, a cloak of invisibility - and a watch that stopped time. However, the return trip would not be so simple.
This, the first volume in a trilogy, tells the story of Master Cheeser Jonathan Bing who sends his best cheeses downriver each year to the elves, in exchange for elfin treasures for the people of Twombly Town. When things go wrong, Jonathan has to set out to deliver the cheeses himself.
