Lea never imagined facing such a drastic turn in her life. Threatened by her own employer, she's forced to take on her identity and marry the son of a wealthy count living in a distant castle. Dark rumors surround Don Moretti, a scientist with a mysterious past, fueling tales of black magic and even suggesting his son might be a demon. However, all these stories pale in comparison to what Lea experiences after marrying Lucca.
Her groom's father, a mad scientist, conducts forbidden experiments in the castle's basement, even on Lucca himself, rendering him a terrifying figure. Dragged against her will into this ominous setting, Lea lives with a man who seems less than human, but she gradually realizes Lucca isn't evil. He's actually a victim of his father's madness, as he imprisons supernatural creatures in the attic.
While planning her escape from the castle, Lea encounters obstacles, as her non-human husband is reluctant to let her go. Moreover, the castle's supernatural creatures make finding a moment of relief nearly impossible.

Catrina’s world shatters when she walks in on Marco in bed with Davina Morano, his rival’s sister. The betrayal cuts deep, but when Marco helped orchestrate a car accident that lands her in the hospital and makes her lose her baby, she realizes she she has to escape him or risk losing everything, including her life.
Now, with Marco relentlessly hunting her, Catrina is forced to rely on Wesley Morano, Marco’s ruthless rival. Wesley offers her a deal: a fake marriage to protect her from Marco’s deadly obsession. It's simple—a temporary solution to keep her alive.
But there’s more to Wesley's offer than meets the eye. While he promises her safety, Catrina knows he has his own agenda. Wesley wants something from this marriage, something that could shift the power dynamics between him and Marco forever. He’s using her just as much as she’s using him.
Still, as the days go on, Catrina can't ignore the undeniable pull between them. Wesley is cold, calculating, and dangerous. But there’s a rawness to him, a darkness that matches her own, something that draws her in even though their marriage is nothing but a cover.
Marco on the other hand is determined to bring her back into his world, to finish what he started. But Wesley will fight to keep her safe. The more time passes, the more Catrina finds herself drawn to Wesley, torn between the man who betrayed her and the one who’s starting to change everything she thought she knew about herself.
Her life remains in danger as she's faced with the ultimate choice.
