Elowen Marsh is the new fifth-year nobody can quite explain. quiet, clever, and far more dangerous in a duel than she should be. Carrying a secret she doesn't even understands. Sebastian Sallow is all charm and sharp edges; the sort of boy who smiles when he's about to break a rule... and breaks it anyway. Elowen and Sebastian become friends first, sharp tongues, steady wands, reckless in the same direction, and bound by a loyalty Sebastian never names aloud. But one Unforgivable Curse leaves a visible scar on Elowen's skin, and their friendship changes. Now the mark won't stop burning... not when darkness draws near... and not when Sebastian stands too near in the dark. The Scar Between Us - a canon-faithful Hogwarts Legacy slowburn romance, where friendship turns into something undeniable, and one Unforgivable moment becomes a bond neither of them can undo.
