George Portman is the New York Times bestselling author of the Blake Knox series, hailed as "The most original thriller series in decades — simply essential."
His work is known for combining the momentum of classic American thriller writing with an unusually close attention to how technology reshapes the landscape of human decision-making — and human vulnerability. The series began with Blast Radius and has continued through Zero Trust, Honeypot Protocol, Acquired Asset, Dark Fiber, Deadman Switch, and Privilege Escalation. Each book stands alone; together they form a portrait of the invisible architecture of modern risk.
Before turning to fiction, Portman spent nearly two decades working at the intersection of financial services and trading technology — an experience that gave him an early, ground-level view of how deeply systems could be gamed by those who understood them from the inside. That period informs not just the technical texture of the novels but their central preoccupation: what happens to judgment, to character, to identity, when the systems we depend on can be turned against us without our knowing.
The Knox novels are set in a world where the old distinctions — adversary and ally, physical and digital, war and peace — have become unreliable. Knox navigates that world by attending to what is actually there. Portman's prose follows the same discipline.
Kill Latency, the eighth novel, is coming soon.
