Book Overview
A tactical nuclear weapon has been smuggled across the U.S.–Mexico border and hidden in the heart of Los Angeles.
The Iranian sleeper agents guarding it have only one instruction: build ordinary lives, disappear into the city, and wait.
For four years, they work, form friendships, and become part of the communities they were sent to destroy. Then the United States launches a devastating war against Iran. As the regime begins to collapse, the long-awaited signal finally arrives.
The weapon will be detonated at dawn.
Seasoned CIA agent Jack Harlan has only hours to locate the bomb before Los Angeles is consumed by nuclear fire. But as he closes in, another battle is unfolding within the cell—a struggle between sworn duty and the lives its members were never supposed to love.
One signal. One dawn. Millions could be gone.
*Dawn of the Crescent* is a tense, emotionally charged thriller about ideology, belonging, betrayal, and the unexpected bonds that can change the fate of a city.
