Winter, 1786. The American experiment is failing. The states are bankrupt, the government is powerless, and in the freezing hills of Massachusetts, desperate Continental veterans are taking up arms against the corrupt courts foreclosing on their farms.

Elias Thorne—a brilliant but shattered former intelligence officer—wants nothing more than to leave the shadows of the war behind. But Alexander Hamilton has one last mission for his most dangerous spy. Sent to infiltrate the rising rebellion, Elias adopts the alias of a ruined, starving farmer to uncover the mob's true strength.

But as he marches through the blizzards alongside men who bled for freedom only to be crushed by peacetime debt, Elias realizes a terrifying truth: the rebels are right.

While his partner, the formidable Agent 355, operates in the warm, wealthy parlors of New York to uncover the money backing the state, she discovers a horrifying conspiracy. The elites of Boston aren't sending police to quell a riot; they have purchased a private mercenary army to slaughter the farmers. And Hamilton doesn't want to stop it. He wants the massacre to happen—a bloody, necessary spectacle to terrify the thirteen fractured states into signing a new, iron-clad Constitution.

Trapped between a doomed army of his former brothers-in-arms and the cold, mathematical ruthlessness of the Founding Fathers, Elias must balance the ultimate equation.

To save the nation, he must betray the very people who built it.
