North Dakota is like nowhere Colleen has ever seen.Vast rolling plains of silvery snow, studded with shimmering black pools. A landscape both beautiful and terrible. The landscape that swallowed Colleen's son. Across town another mother searches for her missing boy. He too went missing from the oilfields where he worked. Alone, these two women will never find out the truth. But if they team up, then maybe this freezing wilderness will give them back their sons.
