One decoded ledger. One subterranean empire. One lethal monster who will burn the city to the ground to keep her safe.

Tamsin Cole lives her life by a strict, unyielding set of rules. As a university archivist, she hides in the climate-controlled dark, convinced that pristine logic and rigid order are the only things preventing her from inheriting her father's legendary madness. But when she uncovers a centuries-old cipher detailing a corrupt elite's underground fighting rings, her carefully constructed world shatters. Suddenly, she's standing in the crosshairs of the Sovereign Court, holding the match that could burn their empire to the ground.

Evander Cross is the kind of story people whisper in the dark. Forged in the blood-soaked dirt of the Court's bare-knuckle pits, he survived by becoming the exact monster they designed him to be. Now the ruthless head of an underworld syndicate, he is violence personified. He expects to retrieve the stolen ledger and eliminate the archivist as a liability. Instead, he finds a woman with a spine of absolute steel who looks at his scarred hands and sees a weapon she can wield.

Dragged into a brutal criminal underworld, Tamsin must rely on the terrifying, fiercely protective syndicate boss to survive. As bullets fly and the city's corrupt billionaires close in, the air between them ignites. Evander is convinced his darkness will ruin her, but Tamsin isn't afraid of the dark—she plans to rule it.

Can their fragile alliance survive a war against the city's most powerful men, or will the explosive, undeniable chemistry between a rigid logician and an apex predator consume them both?
