The moon pool

the long version

North Dakota is like nowhere Colleen has ever seen. Vast rolling plains of silvery snow, studded with shimmering black pools, lit by occasional flares of orange light. It is a landscape both beautiful and terrible. It is the landscape that swallowed her son. Across town, another mother also searches for her missing boy. He too went missing from the oilfields where he worked. And no-one - not his employers, not the police - seems to care that he is gone. As long as they are alone, these two women will never find out the truth. But if they team up, and help each other, then maybe, just maybe, this freezing wilderness will give them back their sons.
