Second Legacy || Cassian Rosier

In the shadow of a rising darkness, choices have consequences-and loyalty can be a dangerous thing.

Fifteen-year-old Aurelia Slughorn, brilliant, sarcastic, and fiercely guarded, returns to Hogwarts for her fifth year only to find the world shifting around her. The Ministry tightens its grip, the Order struggles to resist, and whispers of rebellion stir in the castle's hidden corners. But nothing unsettles her more than Cassian Rosier: charismatic, unwavering, and dangerously devoted to a cause that terrifies even those who should know better.

Cassian's legacy is his father's-one of Voldemort's most loyal followers-and the moment he offers himself to the Dark Lord, the line between loyalty and obsession is drawn in stone. Aurelia is drawn into his orbit, challenged by his certainty, seduced by his calm and confidence, and slowly, imperceptibly, begins to question her own boundaries.

As the walls of Hogwarts close in and the threat of war looms, Aurelia and Cassian's bond deepens-quietly, privately, irreversibly. By the time the world demands their allegiance, they will have crossed lines neither of them can uncross. Love, power, and ambition intertwine, and in the heart of the storm, one truth becomes undeniable: some thorns, once entwined, cannot be separated without breaking.

Part of the 'Second Series'. The 'Second Series' is a series of four books, each having an oc in each Hogwarts house. They can be read in any order as they are all happening within the same timeframe. If I was to recommend reading any way I would do a tandem read between the books, reading them by date. But if you would like to read them one at a time my suggestion would be reading them in this order: Second Chance, Second Sin, Second Haven, Second Storm.
