Nightlord: Mobius (Hardcover) (ISBN-13: 9780578542676)

Faced with war and the end of the world, Eric--or Halar the First, King of Karvalen--must find a way to stop a godlike entity bent on his destruction. He must save everyone he loves, and, perhaps, even save himself. His quest will be no easy thing, not a straight line to his goal, but will lead him on an epic journey. It will take him farther from everything he has ever cared about before he can even begin to come home.
