Fall of Creation — Kenneth McDonald

In the final book of The Godswar trilogy, the mad god Hailidel is nearing the fruition of his plan to undo the work of the Creator and seize the greatest power of the universe for himself. But even as Hailidel moves his mortal pawns into position for the final push, the other gods' Chosen are rallying their own forces to stop him. As the armies of the western nations march to war, Izandra Colton, Robert Small, Ahlen Corander, and the other Chosen must fight their own battles against an enemy that will stop at nothing to gain his ends -- even the destruction of the world itself.
