Born and raised in the violent days of the Labor Movement, in 1920's New England, Robert Henry Pearce falls in with a group of "bomb-throwing" anarchists and agitators determined to bring about the collapse of industrial civilization. After meeting and befriending Sacco, Vanzetti, Luigi Galleani, and his gang, he becomes embroiled in the dangerous, and terroristic, exploits of the class war anarchists inhabiting the greater Boston area. But, as perilous as these activities are, they're the least of his concerns because Robert Henry Pearce has a much more serious problem.
Haunted by increasingly intense cravings, Robert is consumed with the baffling and overwhelming need to feed upon his fellow humans. What is more, satisfying this hunger triggers the onset of numerous supernatural abilities, powers which enable him to perfect his predation of the men he selects as his victims, the many racist sheriffs, judges, Pinkertons, military men, and union-busting robber barons of the burgeoning Industrial Age. Frantically researching the changes that are slowly overtaking him, Robert reads everything he can find, hoping to shed a light on the incredible and horrifying transformation happening around him and inside him.
But perhaps the most disturbing developments are the terrifying, prophetic, dreams of a looming apocalypse, the extermination of humanity by beings so hideous and familiar that Robert can barely bring himself to contemplate them. That is, until he befriends an introverted eccentric named Howard Lovecraft, who is suffering similar premonitions and enhancements. As these two attempt to unravel the global nightmare unfolding around them, they are visited by inhuman beings so frightfully strange, so inconceivably ancient, and hostile to humanity, that both men are slowly driven insane, undermining their friendship, and sending each into his own living nightmare. Fleeing into the wilderness, and meeting up with other enhanced anarchists, enemies of civilization itself, Robert resolves himself to unravel the cosmic conspiracy, to learn the mind-bending truth that underlays his transformation, the civilization he has always hated, and, ultimately, the universe itself.
