John Michael Hadley writes thrillers about the systems that keep powerful people safe, and what happens when those systems fail. His work explores the quiet spaces where technology meets tradecraft: satellite networks, biometric surveillance, and the vulnerabilities hidden inside the infrastructure we trust. The Guardian Protocol is his debut novel — a story that began with a simple question: what if the watch designed to protect you, was the thing that gave you away? The answer took him from a Californian server room, to Vatican back corridors, to the hills east of Amman. He is currently at work on the sequel; "Dead Frequency".
