William hated the mafia more than anything. Haunted by the brutal death of his sister, the young officer accepts a dangerous mission to infiltrate the notorious Tiger Fangs gang and steal a file that could bring the entire mafia empire crashing down.

Enemies close in from every side with traitors hiding in plain sight and allies with knives behind their backs. Lies and deceit weave the chains tighter and William finds himself trapped in a deadly dance of power, passion, and betrayal. In a world where love is a weapon and trust is a luxury, William must decide. Was Dante his ruin, or the only one who could save him?

For five years, Mira poured her obsession into The Reckoning of Caelen Mors—a dark fantasy about a ruthless duke and the woman he becomes dangerously fixated on. At 2:47 AM, exhausted and alone, she died at her laptop. Her final words still glowed on the screen: "Duke Caelen finally showed her his true face. It was nothing like she imagined." She woke as Isadora Vess—the secondary character from her manuscript—in a silk bed, in a monster's house, with servants calling her by a name she'd invented. The problem: Mira remembers writing this world. She knows every dark secret. She knows how the story should end. Except her memories are fractured. The manuscript was never finished. And the characters have evolved without her input, making choices she never wrote, saying things she never scripted. Worse—Duke Caelen knows she's different. He's been waiting for her. Across seventeen timelines, he's seen her arrive at this exact moment. And in three of them, everything burned. Now Isadora must navigate a world she created but no longer controls, surrounded by men who each want to use her—a charming prince offering escape, a dark count offering power, and a villain offering the only thing that might be true: the answer to why she's here, and what happens when an author gets trapped in her own story. Because in every version where Isadora arrives, the empire falls. And Caelen has been waiting a very long time to see which ending she'll choose this time.

Her name was Cathedra. Leave her last name blank, if you will. Where normal people would read, "And they lived happily ever after," at the end of every fairy tale story, she could see something else. Three different things. Three words: Lies, lies, lies. A picture that moves. And a plea: Please tell them the truth. All her life she dedicated herself to becoming a writer and telling the world what was being shown in that moving picture. To expose the lies in the fairy tales everyone in the world has come to know. No one believed her. No one ever did. She was branded as a liar, a freak with too much imagination, and an orphan who only told tall tales to get attention. She was shunned away by society. Loveless. Friendless. As she wrote "The End" to her novels that contained all she knew about the truth inside the fairy tale novels she wrote, she also decided to end her pathetic life and be free from all the burdens she had to bear alone. Instead of dying, she found herself blessed with a second life inside the fairy tale novels she wrote, and living the life she wished she had with the characters she considered as the only friends she had in the world she left behind. Cathedra was happy until she realized that an ominous presence lurks within her stories. One that wanted to kill her to silence the only one who knew the truth.

She thought she had it all—a peaceful life, a loving relationship, and a future she could finally count on. But everything shattered the moment she discovered the truth. He never planned to stay. He never planned to love her. He only wanted the child. Forced to make an impossible choice, she vanished, determined to protect the life growing inside her. For years, she lived in silence, hiding the truth, raising a secret no one could ever know. But fate has a cruel way of circling back. When the past resurfaces in the most unexpected way, everything she fought to protect hangs in the balance. The lies. The love. The billion-dollar secret. Some stories aren’t meant to stay buried. And some truths refuse to stay hidden.

As the ruthless heir to the Vitale empire, he has one mission: find The Ledger and use her to crush his enemies. But the woman he finds isn't just a weapon—she’s the only person who makes him feel human. Now, Dante faces a choice: use her to win a war, or start one with every family in the city to keep her safe. But Iris is about to learn that her protector is the same boy who survived the fire that killed her mother. And in the mafia, the only thing more dangerous than a secret is a man who will burn the world down to keep it.
