HISTORY IS WRITTEN BY THE VICTORS. BUT THE RECEIPTS WERE KEPT BY A PROOFREADER.Seville, 1492. Lorenzo is a man of ink and silence, a proofreader in the Inquisition's scriptorium. His job is to correct the Latin of the Church's holy decrees. But when he finds a jagged margin note in a condemned book-Sanguine negotiantur (They trade in blood)-he uncovers a typo in the moral fabric of the world.The Spanish Inquisition isn't just saving souls; it is liquidating assets. The fires of the Auto-da-fé are merely the furnace for a massive money-laundering operation designed to fund the most expensive gamble in history: the voyage of Christopher Columbus.Armed with a stolen ledger that proves the Holy See is financing the enslavement of a New World before it's even discovered, Lorenzo flees to Rome. There, he must infiltrate the deadly Conclave of 1492 and face the rising monster, Rodrigo Borgia.From the sewers of the Vatican to the deck of the Santa Maria, Lorenzo becomes the accidental auditor of the Apocalypse. He is the only man standing between a "Golden Age" of discovery and an Iron Age of greed.He can't stop the ships. But he can try to edit the contract.
