At seventeen, the realm of faery is the only world Celeste knows, and she aspires to become as close to a faery as a human may. But daunting revelations made by her dying mother knock her plans off course.

Orphaned and anxious to establish where she fits in, Celeste's convictions waver. Is she the human princess her mother raised her to be, or is she the human-faery she longs to become?

Is she to avenge the wrongs done to her parents by an evil sorceress? Or should she wash her hands of the human race?

Is she to honor a betrothal she's known nothing about? Or should she keep at the side of the true love that recently walked into her life?

Celeste chooses to be the avenger of her parents, even if it means she must acknowledge her place as the rightful heiress of Santillán.

Urged by the faery, Nahia, and championed by the faery court and her true love, Celeste sets out to expose the deceitful sorceress, Arantxa. She trusts that nothing can keep her from returning to the realm of faery, nothing that is, until the identity of her betrothed becomes known.
