Gnomon by Nick Harkaway

In a future where the all-seeing System monitors every aspect of life, a detective named Mielikki Neith is tasked with investigating the death of a dissident named Diana Hunter. As Neith delves into Hunter's mind, she encounters a labyrinth of interconnected narratives spanning different times and realities, each revealing layers of truth and deception. Through these stories, the novel explores themes of surveillance, individuality, and the nature of reality, challenging the boundaries between the observer and the observed in a world where privacy is a relic of the past.
