A radical Muslim group has dedicated itself to the restoration of the Caliphate, a global Islamic empire based on cruel medieval values and the conquests of the faith's glory years. These true believers will stop at nothing, including assassinations and terrorism, to achieve their goal. Standing in their way is Steve Church, just a U.S. businessman in Paris who never expected to be recruited by the CIA as an undercover operative. But now, with his life on the line, with the fate of nations at stake, and with the safety of his beautiful Kella in jeopardy, Steve must dive headlong into a desperate struggle to prevent mass destruction. The Caliphate is a whirlwind adventure, bristling with exotic locales, dangerous and desperate characters, and international intrigue, all crafted by a former master spy who has experienced similar dangers and challenges firsthand.
