A dying king. A captive chemist. A lethal equation that will burn a syndicate to the ground.
Vero Malaspina is the apex predator of Novara Isle. As the Sovereign Capo, his absolute rule is enforced by brutal kinetic violence and terrifying intellect. But when a rival matriarch targets him with Acheron 7 a weaponized, incurable neurotoxinthe countdown on his reign begins. Refusing to choke on his own decaying synapses, Vero hunts down the only intellect capable of rewriting his biology.
Orezia Parni is a ghost. Known in the subterranean Warrens only as the Sanitizer, her brilliance in molecular chemistry is rivaled only by her instinct for survival. Dragged from the shadows and locked inside a hyper-sterile penthouse laboratory, she is given a simple, impossible ultimatum: synthesize a cure, or die with the Capo.
But the sterile boundaries between captor and captive quickly denature. As Orezia engineers the daily chemical bridges keeping Vero alive, their forced proximity violently evolves into a dark, intoxicating power exchange. He demands her absolute submission to his territory; she holds the literal syringe that keeps his heavy heart beating.
With the D'Agostino empire closing in to finish the assassination, Orezia must force a permanent cure before Vero's neurological network completely collapses. Yet, tethering the monster to reality requires a terrifying realization-because once the Sovereign of Novara Isle is cured, he will never let her go.
Vow of Reckoning is a gritty, high-stakes mafia romance featuring a possessive, morally black Capo, lethal power dynamics, and a brilliant, unyielding heroine. Kink-adjacent, chemical-laced tension, no cheating, and a dark, devoted happily-ever-after.
