‎One drop of poisoned wine shattered an empire, turning Marcelo Moretti into a cold, mechanical monster bent on absolute vengeance. Fifteen years later, he captures Valeria, a woman hiding behind a forged identity, locking her in a ruthless psychological crucible to break her spirit.‎Yet, behind the reinforced concrete walls, a suffocating, volatile attraction ignites between a captor who swears he cannot feel and a captive carrying a darker history than he knows. As invisible armies mobilize and a devastating betrayal looms, their dangerous friction sparks an uncontrollable wildfire.‎In a world built on stone-cold cruelty, survival demands a passion more brutal than the war that birthed it.‎

‎To the human world, he is Valen Vance, the ruthless and feared gangster ruling the rain-slicked alleys of San Cristóbal de las Sombras. But deep in the darkness, he is Valerius Dragomir, the absolute Vampire King. Two centuries ago, a human betrayal froze his heart, turning him into a merciless monster who views humanity as mere cattle or tools.‎Everything changes the night Aria Linley steps onto the stage of his exclusive club. Aria is a pure 22-year-old singing with a broken soul, desperately seeking money to pay for the medical treatment keeping her terminally ill mother alive. When her voice resonates, it carries a celestial frequency that forces Valerius's dead heart to beat for the first time in two hundred years. Believing she is a trap set by his enemies, Valerius tries to buy her night, but a disgusted Aria spits in his face and rejects his money.‎Tragedy strikes Aria when she discovers that her boyfriend is not only unfaithful with her best friend, but has stolen her late father's music studio to hand it over to an enemy cartel. Hunted by hitmen on a stormy night, Aria is saved by the Vampire King himself in a brutal massacre. But the demon's salvation comes with a price. To save her mother and reclaim her legacy, Aria must sign a blood contract with two unbreakable rules: in private, she must sing to soothe the monster's thirst; in public, she must wear his diamond ring and act as his submissive, devoted fake fiancée. Trapped in a cage of luxury and danger, Aria will learn that the most dangerous game isn't surviving the mafia—it's preventing the devil from stealing her heart.‎-----------------------------‎‎
