Enchanted, Inc.

Katie Chandler had always heard the 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 either.
There, seemingly out of the blue, Katie gets a job offer from Magic, Spells, and Illusions, Inc., a company that sells 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 . . .
