Most humans have forgotten their sparkle . . . hypnotized by the darkness that obscures it.

Twelve-year-old Cara O'Reilly always thought her father was teasing when he said she and her sister had fairy magic. But it's been nearly a week since he went on a mountain hike and vanished-right after an argument with Cara. She wished him gone, and now he is.

Cara's little sister Bri hasn't spoken a word since his disappearance. In fact, Cara feels like her whole family is under a curse. And it seems like all the adults in their family are keeping some sort of secret. Her world further tumbles into chaos when, after a close encounter with a living, breathing fairy, Cara realizes the old stories are all true. Now, she must find the door to the Otherworld to retrieve an ancient treasure. But can she battle the darkness to save her family-and the entire world?
