No matter how hard he tries, Jimmy Yee cannot die. A noose around his neck, a razor across his wrist, and even a bullet to his head all yield the same results: each time he awakes, miraculously unharmed, in his shabby room at the Sunbeam Motel. For reasons he doesn't understand, Jimmy has just become the world's most dangerous man. Using only his mathematics training and his complete lack of scruples, Jimmy must push himself to his mental limits to stay one step ahead of the elite team of intelligence operatives devoted to the single goal of capturing him alive. From the brilliant and profane mind of Jason Shiga comes Demon: a four-volume magnum opus about the unspeakable chaos that one indestructible man can unleash on the world and the astronomical body count he leaves behind.
