Voice Books in Order

The Voice series blends gangland tension with psychological suspense, following the Mason family and the psychiatrist who studies them. Across two books it asks whether violence is born, made, or something more complicated.

Voice Of Reason begins with Dionne, who believes she has married into the good life. Her husband Luke Mason owns nightclubs, and a quiet promise in her ear suggests she will have money, a big house and security. Everything changes when they become parents to twins and a member of the wider Mason family is murdered. The police bring in Dr Katherine Renee, a research psychiatrist whose life’s work has been hunting for evidence of a so‑called Gemini Gene in high‑functioning psychopaths.

As Dr Renee interviews the family, she starts to suspect that someone else is running a far more sinister experiment in the background. The investigation slides from a straightforward homicide inquiry into something that touches on genetics, manipulation and the question of who is really pulling the strings in the Mason household.

In Voice Of Rage, time has passed and the family are trying to move on after multiple deaths, but the past refuses to stay buried. A schoolgirl is found dead in nearby woods and the finger of blame slowly swings toward Harley Mason, a teenage girl people either fiercely love or deeply fear. Detective Lewis Sanders struggles to accept that someone so young could be responsible, yet the discovery of a second body makes it impossible to ignore the pattern.

Meanwhile Dr Katherine Renee, forced to abandon her formal study of the Gemini Gene, is coming apart in her own way. Convinced that Harley is dangerous, she pushes the police to see what she sees, even as she begins to question her own memories and motives. The line between objective science and personal obsession grows increasingly thin.

Together the books create a tight, unsettling arc that still connects to Kerry Barnes’s wider world of clubs, crime and family power struggles. The focus here, though, is on the psychology behind violence—how far people will go to prove a theory, to protect their children, or to silence a voice that threatens to reveal too much.
