Zara Reyes is a prison therapist. Matteo De Rossi is a mafia heir with a body count. She's supposed to stay detached. He's not supposed to care. Neither of them follows the rules. When Zara is assigned to Halworth Correctional Facility, she expects the usual-cold stares, heavy files, and men too far gone to reach. She doesn't expect him. Matteo is the kind of man they warn you about: dangerous, intelligent, and still terrifyingly charming while cuffed to a table. But as sessions turn into something messier, darker, and more intimate than either of them intended, Zara finds herself pulled into a world of secrets, power plays, and bloodstained loyalty. He sees her. She can't look away. And in a place where even the walls have ears, falling for the devil might be the last mistake she ever makes. Perfect for fans of morally gray men, forbidden romance, and slow-burn tension that turns lethal.
