Fire and Ambition

Cassiopeia Black, orphaned since childhood, has always lived in the shadow of a dark past. The daughter of Regulus Black, she was raised with the weight of her Death Eater lineage, which has led to her being marginalized and mocked, especially by Fred Weasley, who never misses an opportunity to remind her of her connection to evil.

But one summer, at the end of her penultimate year at Hogwarts, her life takes an unexpected turn: the Order of the Phoenix, the resistance group against Voldemort, arrives at her home. Among them is a figure she's always tried to avoid: her uncle, Sirius Black. Never visiting her, never showing interest, he now seems to be part of a larger plan that directly involves her.
Cassiopeia discovers that her fate is tied to a truth that no one has ever dared reveal. As dark secrets hide within the walls of her home and tensions rise, the girl must make a choice: continue to live in the shadow of her family or face the truth, with all its consequences. But something doesn't add up, and as she tries to navigate between truth and lies, Cassiopeia uncovers that her life might be the missing piece in a game much bigger than herself.
Her encounter with Fred Weasley, who has always tormented her, turns into something mysterious. But why does Fred seem to know more than he lets on? What is he hiding about his connection to the Order and her own family?

The question tormenting Cassiopeia is: can she really trust those around her, or is she about to be betrayed by the one she least expects?
