She was never supposed to matter. The novel never gave her a name worth remembering. After dying in a mundane accident, twenty-three-year-old Clara Quinn opens her eyes inside the pages of the fantasy novel she despised most — reborn not as the heroine, not as the villainess, but as an unnamed background character fated to die before the story even begins. Her plan is simple: stay invisible. Attend the Imperial Academy of Asterveil, avoid every named character, and quietly survive a plot designed to destroy everyone foolish enough to interfere. That plan lasts exactly one day. During the entrance ceremony, Lady Morwen Ashvale — the infamous crimson-eyed prodigy that even crown princes fear — steps off her platform, walks past every noble heir waiting for her acknowledgment, and stops directly in front of Clara. "You belong to me," Morwen says, loud enough for every student in the hall to hear. "Do not forget it this time." This time. Clara has never met this woman in her life. Yet Morwen looks at her as though she has been searching for centuries. As shadows begin stalking Clara through the academy's cursed corridors — as the original story fractures and rewrites itself around her — Clara uncovers the truth that should be impossible: Morwen has lived this story hundreds of times. She has watched Clara die in every single one. And in every timeline where Clara falls, Morwen burns the kingdom to ash. She is not obsessed. She is grieving. She has always been grieving. And this time, she refuses to lose again.
