A former spy must stop a terrorist plot to unleash a deadly plague across the world in the New York Times bestselling author's "page-turner of a thriller" (BookReporter.com).
Ryan Kealey has no doubt that the forces seeking to tip this teetering world into chaos are only getting better equipped-and, most terrifying of all, more patient. And despite all the ELINT, the all-seeing electronic intelligence gathered at Langley, nothing stops a devastating attack from ripping through the heart of San Antonio, Texas.

Wrenched from retirement to work the Texas tragedy, Kealey learns of a far greater threat in the Middle East. A radical terrorist group claims possession of a powerful ancient relic, the Staff of Moses, which they will use to unleash plagues across the globe. To avert unimaginable devastation, lone-wolf Kealey, armed with little more than intuition, must prevent a disaster of biblical proportions that may well be inevitable.
