The Book of the Living, Book 1: The Eighth Power by Paul Lytle
Summary: A dark conspiracy takes the lives to two Prophets, and their impressive powers have been passed on to another generation. The remaining Prophets have left the Tower to seek the two infants who will replace their fallen allies, but so are the wicked ern seeking the children, and no one is quite sure why. The world is rocked as the battle spreads across the land, and no one seems able to stop it.
Meanwhile, in a tiny farming village, Barrin Iylin is left to raise his new son alone when his wife dies in childbirth. Such a task would be hard enough, but Barrin soon finds out that the ern are targeting his son and any others born on the same day. Could it be that his son is one of the new Prophets? And whether or not he is, how can a poor farmer hope to protect the boy against an army? The sweeping adventure of The Eighth Power begins here, with a heartbroken man who never thought nor desired to be caught up in a war, and yet can do no other if he wants his son to live.
