The Wizard and the Frog

An incompetent wizard turned my girlfriend into a frog, and that's just the beginning.
The name's Jack and I hunt monsters for a living. I've been doing this for a while, but my associate is new. Dormuris is an elf I rescued from a troll, and he's a wizard. Sort of. He's not the best with magic, and he accidentally turned my girlfriend into a frog.
In order to reverse the spell, we have to seek out a real wizard. The guy who offers to help is an oddball, but so long as he can turn my girlfriend back into a human, I can deal with it. He wants a golden egg and a unicorn. Say what now?
I thought my life as a monster hunter was chaos, but I was about to see just how crazy things could get.
Minotaurs, goblins, a singing sword … yeah, you read that right.
If we don't get the items the wizard needs quickly enough, my girlfriend will end up being a frog permanently. And that wouldn't be good for anyone, especially me.
