With Belkin's Pass overrun by vampires and wolves, Josh Stanton, his lover, Dex, former saloon girl Glory, and US Army Sergeant Walker Maxwell, are forced to flee to the abandoned Fort Emmerick. There, they make plans to take the battle to Balthazar's cave in order to stop his plot to turn every human into a vampire.
But much stands in their way. Josh must learn to control his ability to raise the dead. The few survivors need to be trained to fight. And they will need a greater number of soldiers in order to triumph over Balthazar and the people he has turned. Their final, desperate battle will soon take place across the unforgiving landscape of Venom Valley, and the outcome will decide the fate of the entire country.
