📅 2022 🎭 Techno-thriller / Spy fiction 🎧 Audiobook available

It's 2028. The world is changing fast — quantum computing is no longer theoretical, cryptocurrency has reshaped global finance, and drone swarms have rewritten the rules of warfare. Jack and Sarah are sibling spies working for Quotient, a covert independent agency operating in the shadows of global intelligence. When a powerful group begins exploiting quantum capabilities in a race toward immortality, Jack and Sarah are dispatched across the globe to stop them — before the world reaches a point of no return.

From the research corridors of MIT and the cobblestone lanes of Oxford to the crater floors of Tanzania and the rocket launchpads of Texas, The Quantum Contingent moves at a relentless pace through real-world locations and cutting-edge technology. Every piece of tech in the book is real. Every location is a place the author has visited himself.
