"You think you’re just my obsession, Siana? No. You’re the blood in my veins, the chaos in my silence. You're not my weakness—you're my war. And I will burn kingdoms, slit throats, and drown in sin before I ever let you go. You are my devotion... the Devil’s dark devotion." It all started with a dare — a kiss on a stranger’s cheek at a lavish resort party. But that stranger turned out to be Devillian Giordano — ruthless CEO by day, feared mafia boss by night. Cold, commanding, and dangerously irresistible, he doesn’t forgive easily… yet something about Siana Aydin begins to unravel him. What begins as a harmless kiss spirals into a twisted web of obsession, secrets, and a deal that cages her in his dark world. But Devillian isn't a hero. He’s the monster at the end of every fairytale. And yet, she can’t look away — drawn to the very danger that should terrify her. Secrets lurk in every corner, enemies plot from the shadows, and through it all, their hearts burn with forbidden passion. She’s his sunshine. He’s her storm. And she’s about to become his dark devotion. She thought it was a kiss. It became a cage. Now, she's the only thing he worships— and the one thing he might destroy.
