The Mage by Jean Johnson ISBN 13: 9780425250853

  Eight brothers, born in four sets of twins, two years apart to the day—they fulfill the Curse of Eight Prophecy. Though no longer trapped in exile, their growing family faces new problems. The worst of those troubles now fall upon the last of the Sons of Destiny… Hope, Morganen’s foretold bride, has finally arrived. But she hasn’t been entirely truthful about herself, and the consequences will stretch farther than even she anticipates. Just as Morg gets used to Hope’s revelation, new enemies arrive on the Isle, seeking to steal away the brothers’ chance at creating a new nation. During their attack, an old foe resurfaces and strikes amid the confusion, kidnapping the final bride-to-be. Either Morg will rescue Hope and help his family complete the Prophecies of the Seer Draganna and the last Duchess of Nightfall, carving a new kingdom in the process…or their enemies will be free to slaughter them all…
