Ivan Volkov is a Russian student in Beijing who discovers an unsolved puzzle in the writings of the 17th-century astronomer Johannes Kepler. He takes the puzzle to a senior scientist in the Chinese space program and declares his intention to solve it. Volkov returns to Moscow and continues his secret work. The puzzle holds untold consequences for space warfare. The years pass, and they are not kind to Volkov. After the loss of his son, a prosecutor who had been too tough on corruption, and Russia’s invasion of Ukraine, Volkov makes the fraught decision to contact the CIA. He writes: Satellites are your enemies, especially your own.... Hidden codes can make time stop and turn north into south.... If you are smart, you will find me.

CIA operations officer Michael Dunne is tasked with infiltrating an Italian news organization that smells like a front for an enemy intelligence service. Headed by an American journalist, the self-styled bandits run a cyber operation unlike anything the CIA has seen before. Fast, slick and indiscriminate, the group steals secrets from everywhere and anyone, and exploits them in ways the CIA can neither understand nor stop. Dunne has never refused an assignment, and his boss has assured his protection. But when news of the operation breaks and someone leaks that Dunne had an extramarital affair while on the job, the CIA leaves him to take the fall. Now a year later, fresh out of jail, Dunne sets out to hunt down and take vengeance on the people who destroyed his life.

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 THE QUANTUM SPY, 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. Do the leaks expose real secrets, or are they false trails meant to deceive the Chinese? The answer forces Chang to question everything he thought he knew about loyalty, morality and the primacy of truth.
