The Tyranny of the Night Glen Cook

At the edges of the world stand walls of ice which push slowly forward to reclaim the land for the night. And at the world's center, in the Holy Land where two great religions were born, are the Wells of Ihrain, the source of the greatest magics. Over the last century the Patriarchs of the West have demanded crusades to claim the Wells from the Pramans, the followers of the Written. Now an uneasy truce extends between the Pramans and the West, waiting for a spark to start the conflict anew. Then, on a mission in the Holy Land, the young Praman warrior Else is attacked by a creature of the Dark-in effect, a minor god. Too ignorant to know that he can never prevail over such a thing, he fights it and wins, and in so doing, sets the terrors of the night against him.
