Source is Mathew S. Williams portrayal of a dystopian future where humanity runs out of water. The first and second part of the book captures the moral ambiguities and human trauma involved with the survival of the human race in a macabre world where there isn’t enough water for everyone to survive. It avoids the simplicities of good versus evil by forcing basically decent humans to face stark choices. which lead them to do horrible things based upon implacable logic and the need to survive. The book presents what will happen if humanity refuses to live within the ecological limits until it is too late, and it effectively captures the horror and cruelity of a situation where people’s most fundamental moral precepts and their very humanity become warped by an inhumane situation. In the book, those characters who cling to their compassion and honor are the ones who commit suicide or go mad.
