The Iron Equation

Calculated Vengeance. Structural Betrayal. Most men in the Mob use lead to settle their debts. Zenith Castellano uses physics. In the smoke-filled social clubs and blood-stained piers of 1920s New York, Zenith is an anomaly. Known as "The Thinker," he doesn’t see a rival gang as a collection of gunmen; he sees them as a structural load that can be collapsed with the removal of a single, vital pillar. While his brother Leon is groomed to be the heir to the Castellano throne, Zenith is the secret architect behind the family’s success—until the family turns on him. Framed and sent to the hell of Sing Sing, Zenith is forced to strip his life down to the bare math of survival. But the math of the underworld is shifting. With the help of Valentina, his razor-sharp wife who runs the "Long Game" on the outside, Zenith orchestrates a series of tactical strikes that will do more than just kill his enemies. It will erase their very foundations. From the claustrophobic corridors of prison riots to the final, catastrophic "tilt" of a multi-ton shipping pier, The Iron Equation is a noir saga of logic, loyalty, and the lethal force of gravity.
