The Accidental Magician

Long forgotten by mankind the world "Fane" lies on the outer reaches of explored space. The planet's peculiar electromagnetic fields slowly destroy electronic devices but in compensation they enhance psychic abilities. Over the centuries humans and the aliens with whom they share the planet have evolved into clans of wizards and masters, dullards and incompetents. Grantin, the nephew of a powerful but harsh magician, seems bound for failure in the magical arts.
In a last ditch effort to salvage something of his family's honor, his uncle gives Grantin an important but simple task, which Grantin manages to screw up in a most dangerous way. Only vast good luck or the appearance of some heretofore hidden magical talents are likely to save him. Luckily for him, Grantin is, unknowingly, on his way to becoming The Accidental Magician.
