World War III was just practice for what's coming. And even those who survived the original firestorm—like John Thomas Rourke—won't have a chance when the next round of carnage begins. But Rourke, ex-CIA Covert Operations Officer, weapons specialist, and survival expert didn't struggle to stay alive in this brutal world only to die in a final holocaust of fire and blood. As six nuclear missiles are poised to start the ultimate conflagration, Rourke's constant quest for his wife and son becomes a desperate mission to save both his family and all humanity from being blasted into extinction. If he should fail, no man will ever walk the earth again—not even The Survivalist.
