When timid maid Isabella stumbles into the wrong room of Luca Moretti’s opulent penthouse, she witnesses a world she was never meant to see: a world of blood, betrayal, and a man feared by all. Luca, the ruthless kingpin of the Moretti crime family, should kill her for what she’s seen. But something about her trembling innocence stirs a part of thought dead. Isabella is captive in Luca's vicious kingdom, fighting to survive as she grows increasingly fearful of him and slowly dies under the weight of a fatal obsession. Tortured by the need to hold onto her and the vow never to be available, Luca is consumed by an unrelenting passion. Assailed by competitors and treachery creeping in among his forces, Isabella is his greatest weakness and his most immense desire. But in a world where love is a vulnerability and trust is a death sentence, can a fragile maid navigate through the underworld of a mafia king? Or will Luca's ruthless world kill them both off before either one is strong enough to confess the desires they're struggling so hard to deny?
