A Theory of Ruin [Tom Riddle]

To the students of Hogwarts, Moon Silverleigh is the portrait of noble perfection. A daughter of one of the Wizarding World's most storied lineages, she is the helpful hand in the common room, the brilliant mind who clarifies a complex charm for a classmate, and the compassionate face of Ravenclaw. She wears her kindness like a royal decree, hiding the fractured weight of her heritage behind a mask of academic grace.

But then there is Tom Riddle.

He is the shadow in the library, a mystery behind a prefect's badge, and the only person who sees her hunger for greatness beneath her friendly facade. While others are charmed by her status or kindness, Tom is fascinated by her secrets and knowledge. In the quiet corners of the castle, they strike a pact. They are partners, seekers of the truth, two brilliant minds united by a desire to fix the world.

As they delve into the forbidden intersection of Ancient Magic and the Dark Arts, Moon believes she has finally found a kindred soul. But as the blood begins to stain the Highland snow and Tom's methods turn from clinical to cruel, she realizes the horrifying truth: shared ambition is not the same as shared principles.
