Discount Armageddon (Incryptid Series, 1) [McGuire, Seanan]

The Price family has spent generations studying the monsters of the world, working to protect them from humanity--and humanity from them. Enter Verity Price. Despite being trained from birth as a cryptozoologist, she'd rather dance a tango than tangle with a demon, and is spending a year in Manhattan while she pursues her career in professional ballroom dance.
