As war rages across the world, a dangerous new entity makes it fearsome presence known in the climactic finale of this epic quest fantasy series. As the Twins continue on their separate journeys to retrieve the Gem of Eternity, the evil Colton continues to wage war on the scattered forces of resistance. But an even more powerful threat is emerging—the Darkening, a terrifying void that encroaches upon the very heart of the land. Stealing memories and thoughts, it threatens life itself. Determined to complete his conquest, Colton sends three abominations to the three Elfin kingdoms, exact replicas of the Elfin sons of the royal families. As they sow the seeds of catastrophe and murder, faith and trust are undermined, and doubt takes root across the world. And all the while, the Darkening gains power none yet understand. The sacred trees are dying. But when another is born, a powerful light illuminates the sky, offering a spark of hope . . .
