For Mason Konrad the future's looking good. Parties, an apartment in the city, a well-paid job in TV, then one night he's attacked. Worse is to come: his attacker looks exactly like him. Soon he will understand that something unique has invaded his flesh - a certain monstrous 'something' that transforms ordinary people into replicas of him that are driven by evil bloodlust. As the body count rises Mason fights to keep one step ahead of the Echomen. Meanwhile, the Echomen not only hunt him, his family and friends, they conduct gruesome experiments on their own kind. They have their own mysterious agenda - and this is identity theft at its most extreme. Plunge in! This is horror loaded with raw power. It's a pinch of Lovecraft. A splash of Rod Serling. A raging storm of nightmare, ferocity and blood.
