The Curse of the Dark Classroom

She came to teach. But the castle never forgets - nor does it forget who she truly serves.
After years in the shadows, Ally Pendragon returns to the world of wizards under a false name. As the new Defence Against the Dark Arts teacher, she takes up her post at Hogwarts - aloof, quiet, conscientious. Hardly anyone suspects who she really is. Or what she really wants.
For behind the façade of the dutiful professor lies more than just a past. While rumours swirl and old names are whispered in the corridors, Ally secretly spins her own plan - one that reaches deep into the heart of history.
What no one must know: her goal lies not in the classroom. But in the deepest dungeons of the wizarding world.
But the longer she stays at Hogwarts, the more a question arises:
How far can you deny yourself before you forget who you were?
