Isdemus places Peter and Lily in Carlion's sister cities for safe-keeping until the war begins. But Peter and Lily have an idea that might enable the Watchers to steal back the fragments, in spite of the Shadow Lord's invincible army. Their plan requires them to travel halfway across the world, to an island largely believed to exist only in Greek mythology. Along the way, however, the Shadow Lord uses a pawn to convince Peter and Lily that they are powerless. Without their gifts of the Ancient Tongue, will either one of them stand a chance?In this gripping conclusion of the Piercing the Veil trilogy, the Watchers and the Shadow Lord both amass their ranks, the battle begins, and the true identity of the Child of the Prophecy is revealed--to the shock of all. less
