Every lock in the world is made of math. And math can be broken.

At 15 millikelvin, in the coldest room on Earth, a machine wakes up.

For years, Elena Vasquez has warned them. In Geneva, in Brussels, in rooms where no one listened. Q-Day is not theoretical anymore. It's a date on a calendar.

When a dilution refrigerator at ARCTIC-9 in Svalbard hits 15 mK and factors a 2048-bit key in under three minutes, the architecture of glass shatters. Banks. Power grids. Governments. Every secret, every file, every lock - open.

James is the only man who knows how to keep the cold from killing the machine. Victor is the man who built it for a different reason. And a one-eared rabbit in a metal box is the only reason any of it matters.

A breathless quantum thriller for fans of Blake Crouch, Daniel Suarez, and Andy Weir.

Inside:

  • A scientifically accurate quantum apocalypse scenario
  • A 72-hour countdown across Geneva, Svalbard, and Sriharikota
  • The day encryption dies
