Unlike typical short story collections, "Zero-Sum" uniquely focuses on the psychological warfare and power dynamics in modern relationships, with each story presenting a different facet of how people compete, manipulate, and struggle for dominance in their personal and professional lives.

The book contains mature themes and complex psychological situations that are best suited for adult readers who appreciate literary fiction with dark undertones and challenging moral questions. Some stories deal with sensitive subjects like stalking, predatory behavior, and suicide.

The title reflects the central theme that runs through all the stories - situations where one person's victory necessarily means another's defeat. Each narrative explores scenarios where characters find themselves in circumstances where mutual benefit seems impossible, leading to intense psychological and emotional conflicts.
