The first shadows fall on a Friday afternoon when a single, dying raven delivers an invitation to the witch, Diana Bishop. It calls her home to the hallowed ground of Ravenswood, to a place and a family she has never known.

And when Diana and her husband Matthew Clairmont learn that their seven-year-old twins must have their magical powers tested, Diana decides to forge a new future for her family, hoping to find answers at the Proctor ancestral home. There, Diana becomes her great aunt Gwyneth's pupil in Higher Magic. And as Diana walks an unknown path, she must journey to some of the darkest places within her family history - and herself - if she is to unlock greater power.

An instant Sunday Times bestseller, The Black Bird Oracle returns to the world of All Souls, sweeping readers back to the Salem Panic to shine a light on the intertwined legacy of the Bishop and Proctor families.
