Charlotte Ivory, a sharp-tongued but anxious Ravenclaw, stumbles into an unlikely sisterhood with three girls from all four Houses: Ember Collyns, Maude River, and Evangeline Clementine. Their friendship becomes the quiet center of Hogwarts, until ancient disturbances begin shaking the castle awake.
As old magic stirs, the girls uncover secrets that weave their lives together, and draw Charlotte into a reluctant partnership (and undeniable tension) with Draco Malfoy. Rivalries, mysteries, magic, and found family collide in a year where Hogwarts remembers everything, including the people it chose to bring together.
