Q-Day: Every Lock in the World Is Made of Math

By Carl Wang

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

At fifteen millikelvin - colder than deep space - a machine wakes up in the coldest room on Earth.

It was called ARCTIC-9. A research project that was never supposed to work.

In three minutes and forty-seven seconds, it factors a 2048-bit key. The unbreakable code that protects banks, power grids, hospitals, and governments. Shattered.

Dr. Elena Vasquez warned them Q-Day was coming. No one listened.

James is the only engineer who can keep the machine from killing itself. Victor is the man who built it to burn the world. And in a cell in The Hague, a folded piece of paper and a one-eared rabbit are the only reasons any of it still matters.

The locks are already open.

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