In a world where being "Rare" means having an identical twin with the exact same personality, Amaris O'Rally has never truly belonged. She knows what society expects-twins should think alike, act alike, be alike. But Amaris isn't like anyone else, and she carries a secret no one can ever discover: the scars left by her stepfather, each one a silent reminder of the five times she barely escaped death. All she wants is freedom. But when she finally breaks away from her past, she finds herself entangled in something far more dangerous. Aubrey Prices, the infamous serial killer haunting Claymore, seeks her help. But Aubrey isn't just a murderer-she's something else entirely, something darker, something Amaris can't quite understand. As she navigates a world where truth is twisted and secrets are lethal, Amaris stumbles upon a terrifying revelation-she has a twin sister. A sister she doesn't remember. A sister whose icy stare hides more than just a fractured past. Because beneath those cold, calculating eyes lies something unnatural, something powerful... something not entirely human. Now, caught between a killer, a twin with unimaginable abilities, and the whispers of a demon lurking in the shadows, Amaris must uncover the truth before it consumes her. But in a world where being Rare means everything, what happens when she realizes she's something even more dangerous?
