The Hardest Drug

In the dark heart of the Cold War, one CIA officer stands between America and a bioweapon apocalypse.

From Bogotá to the trackless jungle, Clara Verona races against time, betrayal, and her own haunted past to stop a conspiracy that could devastate America’s cities. Against communist guerrillas and cocaine smugglers, her only allies are an ex-lover who might not be so ex, and a cocky pilot with a shadowy past.

The Hardest Drug — a pulse-pounding Cold War thriller of espionage, betrayal, and redemption. Perfect for fans of Tom Clancy, Robert Ludlum, and Vince Flynn.

Also known as The Deepest Cut Book 2.
