Quantum Breach

"Quantum computing is the atomic bomb in global information warfare. Its key is this man-made diamond," Larry said, " and we can't just steal it. So we need to hack into the network to get the diamond's code."

Larry paused, letting Tanner process what he had been told. "That's why you're here."

Tanner Zane is a Mormon with a secret criminal past. Nobody suspects that before his religious conversion he had hacked into thousands of computer networks across the globe. But Tanner's guarded past is exposed when he's kidnapped and forced to hack into an impossible target--Los Alamos National Labs.

Inside is a prototype quantum computer powerful enough to crack the digital safeguards of the Internet. When Tanner learns that cyber-terrorists will use it for massive identify theft and corporate espionage around the world, he deliberately engages in an intellectual battle with his captors to prevent them from obtaining the device.

The Quantum Breach makes you wonder just what you would be willing to sacrifice in order to save the world.
