A lethal biological pathogen. A rogue mastermind. A sovereign holding the key to survival.

When a CIA station chief is sent on a mission to find an ancient record about a deadly disease, the heiress of the Zaragoza fortune stands in his way. But fate brings them together as chaos sweeps the globe and hostile military regimes and covert deep state networks crumble in a matter of hours.

Together with an elite joint task force, they race against time to contain a bio-hazard wildfire, only to discover that the outbreak is no accident and a bio-weapons strategist is pulling the strings in the greatest non-attributable geopolitical purge in human history.

From the sun-drenched, tradition-steeped agricultural estates of Batac and the marble halls of Jolo to subterranean safehouses and bloody crossfire, The Heiress of Zaragoza delivers a sweeping international journey of tactical suspense, elite team camaraderie, and razor-sharp banter between fierce heroines and the dangerous men who fall for them.
