The year is 1491, and sixteen-year-old Isabella Obrigon is kidnapped from her privileged life. When told she isn't of Spanish noble blood, but rather the child of a Jewish woman who died in childbirth, Isabella becomes personally embroiled in the terror of the Inquisition. She finds herself imprisoned in the famed fortress of Alhambra, where an encounter with mysterious and dashing Miguel Costa impels her to accept having been adopted and to vow to find her birth parents. The Spanish monarchs fight to unify Spain as a Catholic nation; as soon as the war is over, the Queen Isabella must fulfill her vow to the grand inquisitor to rid Spain of all heretics. She decrees the Jews' exile. Isabella Obrigon must now decide whether to follow her heart and join her endangered brethren seeking exile, or stay and live a lie.
