Beukes uses time travel to highlight the shifting social landscapes of Chicago. From the gritty 1930s to the burgeoning punk scene of the 90s, the setting reflects the evolution of the city and its people.

The book remains a landmark in modern speculative fiction, praised for its ability to balance high-concept sci-fi with grounded, empathetic storytelling.

Kirby is the only one of Harper's intended victims to survive his brutal attack. Driven by a need for justice and an understanding of the impossible circumstances of her assault, Kirby becomes an intern at the Chicago Sun-Times . Alongside Dan Velasquez, a cynical former homicide reporter, she begins to piece together a series of cold cases that span nearly a century.

As Harper stalks his victims through the 20th century, he leaves behind "anachronisms"—objects from other times—as twisted trophies and clues. However, his spree encounters an unexpected obstacle in Kirby Mazrachi.

The novel critiques the trope of the "disposable" female victim in thriller fiction. By giving the victims distinct voices and backstories, Beukes ensures their lives are felt as deeply as their deaths.

The "shining" quality of the victims represents their untapped potential and the vibrant lives they lead. Harper’s obsession with extinguishing this light explores the impact of violence on progress and the future.
