(Book)

Includes bibliographical references (pages 378-379).

"Isabella is barely a teenager when she becomes an unwitting pawn in a plot to dethrone her halfbrother, King Enrique. Suspected of treason and held captive, she treads a perilous path, torn between loyalties, until at age seventeen she suddenly finds herself heiress of Castile, the largest kingdom in Spain. Plunged into a deadly conflict to secure her crown, she is determined to wed the one man she loves yet who is forbidden to her--Fernando, prince of Aragon. As they unite their two realms under "one crown, one country, one faith," Isabella and Fernando face an impoverished Spain beset by enemies. With the future of her throne at stake, Isabella resists the zealous demands of the inquisitor Torquemada even as she is seduced by the dreams of an enigmatic navigator named Columbus. But when the Moors of the southern domain of Granada declare war, a violent, treacherous battle against an ancient adversary erupts, one that will test all of Isabella's resolve, her courage, and her tenacious belief in her destiny."--Page 4 of cover.
