About this book

A bioweapon triggers a global epidemic that sparks World War III in this thriller by Clay Martin, author of Last Son of the War God. Derek Martell works at a fuel point in Eastern Iraq, a far cry from his former life. After a sandstorm, he awakens to find an apocalypse underway. A worldwide epidemic is spreading, with only genetic Arabs appearing immune. Historical grievances are being settled as the balance of power shifts dramatically. Facing limited options, the Western world considers deploying a weapon of radiation and fire—a tool used only twice before. Derek joins other survivors in a desperate race through the burning desert against the clock. A counter strike looms, and local forces pose an immediate threat. His only hope lies in finding a plane, but first he must evade the Sword of the Caliphate.
