A hyper-fast quantum computer is the digital equivalent of a nuclear bomb; whoever possesses one will be able to shred any encryption and break any code in existence. The question is: who will build one first, the U.S. or China? In this gripping thriller, U.S. quantum research labs are compromised by a suspected Chinese informant, inciting a mole hunt of history-altering proportions. CIA officer Harris Chang leads the charge, pursuing his target from Singapore to Mexico and beyond.
