Working a lonely night shift at an animal clinic, veterinarian Scarlett Reed saves the life of a heavily wounded stranger, only to realize he is Leon Volkov, a feared and ruthless mafia boss. Because she looked directly into his face during the emergency surgery, Leon refuses to let her walk away into ordinary civilian life. Presenting her with a terrifying ultimatum, Leon forces Scarlett into a contract marriage, demanding that she live under his armed protection to keep his enemies from using her as leverage. Trapped in his fortified penthouse, Scarlett is thrust into a lethal world of criminal cartels, shadowy conspiracies, and escalating danger. Yet as Leon repeatedly risks his own life to shield her from rival syndicates, Scarlett finds herself fighting a forbidden attraction to the dangerous mobster. With thirty days left before her fate is sealed, will Scarlett choose her freedom or Leon?
