indelible.

For fifteen years, Madeleine Hanami Riddle has lived an ordinary life-school buses, crowded classrooms, detentions she absolutely deserved, and a mother who insists on rules without explanations. Her past is a blank space filled with half-truths and a father whose name is never spoken for long.

Then, on September first, Madeleine walks into a wall at King's Cross Station and vanishes.

She wakes to steam, scarlet trains, and a world that was never supposed to find her. Hogwarts School of Witchcraft and Wizardry has no record of her existence. No letter. No name on any list. And yet, magic responds to her like it has been waiting.

Sorted into Slytherin by accident-Madeleine must learn the rules of a world that distrusts what it cannot categorize. As Dolores Umbridge tightens her grip on Hogwarts and the past begins to stir, whispers follow her through stone corridors: Who is she? Where did she come from?

What no one knows is that Madeleine's existence is not a mistake-but a scar. A living reminder of a bloodline that tried to erase its own weaknesses and failed.

Some names are written in history.
Others are crossed out.
But some things are indelible.
