It's been said if two or more people strongly agree on any one thing, no matter how unlikely, that thing will come to pass. When art lovers and critics alike unanimously acclaim Sam Forbes' monsters in his Dozen Dreadfuls series as real enough to step right off the canvas and into the world, they unwittingly unleash a rash of gory killings and a plague of terror as well.  As the only living human who knows what is happening, Sam sets out to make up for the damage his work has caused at the risk of losing his first and best claim to fame. Can he save the world from the horror in time, and what will he have left if he does?
