From the Sydney, Australia home of a grandmother she believes is a witch, fifteen-year-old Reason Cansino is magically transported to New York City, where she discovers that friends and foes can be hard to distinguish.

In a world in which everyone has a personal fairy who tends to one aspect of daily life, fourteen-year-old Charlie decides she does not want hers--a parking fairy--and embarks on a series of misadventures designed to rid herself of the invisible sprite and replace it with a better one, like her friend Rochelle's shopping fairy.
