Ye Gods! — Tom Holt

Being a hero bothers Jason Derry. It's easy to get maladjusted when your mom's a suburban housewife and your dad's the Supreme Being. It can be a real drag slaying monsters and retrieving golden fleeces from fire-spitting dragons, and then having to tidy your room before you can watch Star Trek. But it's not the relentless tedium of imperishable glory that finally brings Jason to the end of his rope; it's something so funny that it's got to be taken seriously. Deadly seriously.
