On the day of her wedding, Elena Bianchi was left standing alone in a church. For the nineteenth time, Don Giovanni Rossi failed to appear. His excuse was the same as always—Lina was 'dying' again. This time, the humiliation went further. While Elena waited in her wedding dress, a video call arrived. On the screen, the lace veil her mother had left her—the one promise Elena had sworn to keep—was being torn apart by Lina’s dog as Lina laughed and urged it on. Giovanni followed with a careless apology. He promised to buy her a better one. That veil had been the last thing her mother ever gave her. Elena did not cry. She did not argue. Instead, she made a call no one in the Italian underworld dared to make. Seven years later, the Rossi family had fallen. Their power was gone. Their allies had turned away. And Giovanni—once untouchable—stood among the defeated, waiting to receive the Donna of the most powerful Mafia family. He never expected it to be Elena. Now married to Rafael Bellini, Elena was no longer the woman abandoned at the altar. She was Bellini’s Donna—calm, ruthless, and beyond his reach. The veil that had once been fed to a dog had become a crown. And the man who had destroyed her was now her enemy. In a world ruled by bloodlines, loyalty, and vengeance, Elena proved one unbreakable truth: A woman cast aside by a Mafia king did not disappear—she rose, and she returned as his reckoning.

He played the role of the devoted, submissive mate, enduring Tristan’s coldness and the stinging scent of another wolf on his husband’s skin. He thought loyalty would eventually win Tristan’s heart. He was wrong. Caught in the act with his ex-lover, Tristan throws a divorce decree at Xender’s feet, choosing a "delicate" omega over the soldier who bled to keep his borders safe. He strips Xender of his title and kicks him out of the Blackmoor Pack House into the rain, calling him a "useless drain on the pack." But Tristan made one fatal mistake: He forgot that Xender wasn't just a discarded mate. He is the most feared architect in the Nightfall Territory. Now, the Blackmoor Syndicate is facing a multi-billion credit collapse, and there is only one man who can save them. When Tristan crawls to the legendary Moonshade Atelier to beg for help, he doesn't find a faceless contractor.

In this mafia werewolf world, if you aren't the predator, you're the prey—and the Ghost has finally come to collect his debt.

“He pressed me to the wall with one hand tight around my throat, the other sliding beneath the thin silk clinging to my skin. I should’ve been begging for help. Instead, my knees went weak when he leaned in, his mouth hot against my ear. ‘Does it hurt, darling?’ he whispered. I shook my head, even as his fingers left bruises. ‘Good. I like it when you take it.’ God, I hated him. God, I wanted him to never let go.” A DARK, EROTIC TALE OF OBSESSION, HUMILIATION, AND HUNGER.
