There was a prophecy. There usually is, in these kinds of situations.
Invictus Kul is an invincible hero, destined to save the world. He even has a piece of paper that says so. But it turns out that knowing you’re invincible rather takes the shine off winning, and life in general.
Death Scream, a wandering barbarian warrior, would like to take rather more than the shine off Invictus’ life. In fact, she’d like to cut it abruptly short, but that can’t happen until he fulfils his destiny and saves the world. Of course, Vic (to his friends, which she isn’t) has no plans to do anything of the sort, so she’s going to have to help him. Or force him.
Along the way she’ll encounter Dark Lords, a nightmarish maid who gets a half-price discount at the opticians, ancient magics, gainfully-employed Orcs, and Union Regulations.
All this and more can be found in “The Zero of Destiny”, a fantasy-comedy that absolutely nobody should take seriously, but everybody should read. Unless you don’t like puns, and/or really like geraniums.
