The Noble House of Black: A Harry Potter Retelling

Zillaria Lestrange Black knows madness is inherited in the Black bloodline.

She's spent seventeen years outrunning it, locking it away behind warm smiles, desperate laughter, and the love of the only family she has-Sirius Black, Remus Lupin, and Harry Potter. But no amount of love can cleanse what's in her blood. No charm can rewrite the fact that Bellatrix Lestrange is her mother. That James Potter is her father. That her very existence is a cruel joke played by fate.

And lately, she can feel it-something inside her is slipping. Shadows stretch longer. Her magic lashes out, sharp and violent, leaving behind a hunger that terrifies her. She feels her mother in the marrow of her bones, in the flick of her wand, in the laughter that sometimes sounds too sharp. She dreams in screams.
She can't let them know. Not Sirius, who looks at her like she's his salvation. Not Harry, who trusts her like a sister. Not Hermione and Ron, who would never understand. Because if they knew-if they saw the cracks-Would they fight to save her? Or would they put her down before she becomes what she was born to be?
