Assassin’s Creed Narrative Director Darby McDevitt Debuts The Halter — A Cyber-Noir Thriller That Explores the Dark Side of Escapism

The Halter(Diversion Books, February 17, 2026) marks the electrifying debut novel from Darby McDevitt, Narrative Director for the Assassin’s Creed video game series and writer of more than 25 acclaimed games, two of which have sold over 25 million copies worldwide. An award-winning storyteller with a global fanbase, McDevitt now turns his mastery of immersive narratives to a high-stakes sci-fi noir that tackles society’s obsession with escapism, the seductive dangers of technology, and the brittle fantasies we build to survive.

Brimming with black humor, hardboiled grit, and a cast of unforgettable misfits, The Halter is a cyber-noir novel that fuses the inventive worldbuilding of Philip K. Dick, the elegiac longing of Raymond Chandler, and the pulse-pounding narrative drive beloved by fans of Ready Player One and Rabbits.

A Detective for the Digital Age

In a world where virtual addiction kills, Kennedy Stark is a “halter”—part detective, part counselor—paid to pull the plug on those lost inside surrogate realities. Haunted by dreams of escaping Earth’s climate collapse for a burgeoning Mars colony, Stark takes a dangerous new case: his long-lost love, software engineer Delia Walsh, has vanished into a project called The Forum.

The Forum is a whimsical and carnivalesque metaverse of seemingly infinite “theaters”—each more bizarre, playful, and perilous than the last. As Stark navigates its surreal landscapes and corrupted experiments, he uncovers a conspiracy that could destabilize not only this seductive digital world, but the fragile society outside it.

A Hybrid of Sci-Fi and Crime Fiction

Though set in the near future, The Halter is classic hardboiled PI noir at heart—featuring a gripping twist and a cast of characters who stumble through their illusions with both tragedy and comedy. With snappy dialogue, propulsive plotting, and speculative imagination, McDevitt delivers a thriller as entertaining as it is unsettling.

A Timely Exploration of Technology

At the core of The Halter is a resonant theme: the unpredictable “desire line” of technological development. In an era when AI, virtual reality, and digital networks evolve at breakneck speed, McDevitt examines how technology, once unleashed, often escapes our intentions—reshaping lives and societies in ways both wondrous and terrifying.
