Majyk by Accident — Esther Friesner

DO YOU BELIEVE IN MAJYK?

Kendar Gangle's the worst student magician on the world of Orbix. He's a flop at mastering Majyk--the stuff that puts spunk in spells--until he chases an Earth cat called Scandal into a Majyk cloud. Now Kendar has the biggest supply of Majyk on Orbix--and an even bigger supply of enemies--including a jealous wizard named Zoltan Fiendlord, a baby-faced barbarian, a diminutive demon, and more...

It's amazing what a little Majyk can do.
