Meet Isabella, a strong-willed woman, an assassin, a hacker, a fighter, and a woman of her words. They said nothing could break her, until he came - Alexander Black. A billionaire in the day and a ruthless mafia in the night. A philanthropist in the light, a heartless murderer in the dark. This is not a story where a strong male character oppresses the poor, timid female character. No, this story is about two - strong, heartless, ruthless, and polar opposites falling in love, hard. Neither one will ever back off nor submit. What happens when all the betrayals, conspiracies and heartbreaks fail to keep them apart when a promise of forever is made?
