On the seventh year after the breakup, I receive a package from Clarence Fraser. All 44 pounds of said package consist of the stacks of chat history I have with him in the past. Soon, Clarence's text appears on my phone screen. "Wanna meet up? I'd like to tell you something." I pause momentarily before responding with a "1". That number signifies rejection. Then, I turn my phone off. After wiping my sweat off with a towel, I pick up another crate of fruits and continue promoting them to the customers loudly, as though nothing has happened. It's been so many years, and I don't know why Clarence decides to text me all of a sudden. Similarly, he doesn't know that I've already become someone else's wife a long time ago.

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.
