The Sword of Cyrus

A weapon smaller than a phone. A threat larger than civilization.

Deep in the Zagros Mountains of Iran, a secretive group calling themselves The Sword of Cyrus has engineered the ultimate weapon—a nanotech nuclear device small enough to fit in a mobile phone yet capable of unleashing the force of seven Hiroshima bombs. Its purpose? To wipe Western civilization off the map.

For Dalir Jahandar, vengeance is more than a mission—it is his destiny. A descendant of kings, he is determined to restore the ancient Persian empire to its former glory. Just as Cyrus the Great conquered Babylon by outwitting his enemies, Dalir and his secretive network of powerful allies will infiltrate their enemies from within, striking when they least expect it.

Daniel and Sarah Rossler, along with their team at the Rossler Foundation, find themselves at the forefront of the battle. Known for their work in archaeology and cutting-edge science, the Foundation is drawn into a global conspiracy where history, technology and warfare collide. With Dalir’s operatives closing in and time running out, they must navigate a treacherous landscape of espionage and betrayal to stop the unthinkable from happening.

Will the Rossler Foundation prevail, or will the world succumb to the devastating power of the Sword of Cyrus?

The Sword of Cyrus is the fourth gripping installment in JC Ryan’s acclaimed Rossler Foundation Mystery series, where ancient ambitions meet modern warfare in a high-stakes battle for the future of civilization.
