Sneaking out of prison isn't easy, unless you are a thief, or a wizard. Luckily, Conn is both! Trouble is, once he's out, where does he go? His home is a pile of rubble since he blew it up doing magic. His master, the wizard Nevery, is furious. With a new order of exile, this time with a death penalty, Conn has never been in such a tight fix.

But Wellmet is in danger from an evil predator coming to destroy the city. Now Conn must set off on a quest to find something that will help him fight back. After an explosive experiment, he follows the call of his magic stone to a distant land. When Conn is swept away in the mouth of a magnificent Dragon, he is to face a power unlike any other... but is he a match for it and can he save his city, and himself, in time?
