DON'T MESS WITH HEXES
Katie Chandler had always heard that New York is a weird and wonderful place, but this small-town Texas gal had no idea how weird until she moved there. Everywhere she goes, she sees something worth gawking at and Katie is afraid she's a little too normal to make a splash in the big city. Working for an ogre of a boss doesn't help.
Then, seemingly out of the blue, Katie gets a job offer from Magic, Spells, and Illusions, Inc., a company that tricks of the trade to the magic community. For MSI, Katie's ordinariness is an asset. Lacking any bit of magic, she can easily spot a fake spell, catch hidden clauses in competitor's contracts, and detect magically disguised intruders. Suddenly, average Katie is very special indeed.
She quickly learns that office politics are even more complicated when your new boss is a real ogre, and you have a crush on the sexy, shy, ultra powerful head of the R&D department, who is so busy fighting an evil competitor threatening to sell black magic on the street that he seems barely to notice Katie. Now it's up to Katie to pull off the impossible: save the world and - hopefully - live happily ever after.
