In this compulsively readable science fiction mystery, a detective addicted to a memory-wiping drug races to uncover a killer’s identity—all while confronting the truths she’s desperate to forget.

In the future, 95 percent of people live happily plugged into a fully immersive Digital world, their physical bodies encased in pods in the monolithic Citadel. Outside, a scattered few live in Analog, the real world: the exiles, the skeptics, and the unlucky ones, like Iraj Mistry, whose neural port failed at birth. Limited to life in Analog, Iraj has become a star detective. Now hunting a high-profile killer, her biggest problem is herself. Addicted to Lethe—a drug dispensed by the police to help victims forget traumatic events—she starts to realize that the holes in her memory may be hiding the very clues she needs.

Structured as six interconnected puzzle-box mysteries that snap together in a final, stunning reveal, The Lethe Killer tracks Iraj’s relentless pursuit of the truth through the overgrown and seedy streets of Analog. Each case is as satisfying as it is surprising, and together they spiral toward the greatest mystery of all: Who is the Lethe Killer?

With the neon grit of Blade Runner and the narrative sleight of hand of Memento, this novel dives into digital dependence and its discontents, the cost of forgetting, and the widening gulf between the plugged‑in elite and those left behind. Inventive, propulsive, and built for reader theories, The Lethe Killer is sci-fi noir that lingers, its twists, worldbuilding, and unreliable detective sparking conversation long after the final reveal.
