'The Black Bird Oracle deftly explores the nexus of memory, history, and parenthood - the magic, pain, and promises mothers pass onto their children. Harkness's lush prose makes a fantastical world real enough to touch' JODI PICOULT

Diana Bishop journeys to the darkest places within herself - and her family history - in the highly anticipated fifth novel of the beloved Number One Sunday Times bestselling All Souls series.

The first shadows fall on a Friday afternoon when a single, dying raven lands on the pavement in front of Diana Bishop, harbinger of an invitation that reads, 'It's time you came home, Diana'.

Diana is a witch and scholar; her husband Matthew Clairmont, a vampire. Their intense love for one another awoke the dark powers within her and dissolved the Covenant between the three species - Witch, Daemon and Vampire - that live alongside humans. Now, the governing Congregation has decided it must test the magical powers of their seven-year-old twins, Pip and Becca. Concerned with their safety, Diana decides to forge a different path for her family's future and travels to Ravenswood, the Proctor family home.

There, Diana begins a new era, becoming her great aunt Gwyneth's pupil in higher magic. It's time to confront her family's past - and her own, inescapable desire for greater power.

Number One bestselling author Deborah Harkness returns to her beloved All Souls world with a triumphant novel that sweeps back to the Salem Panic and illuminates Diana's family history in new and thrilling ways.
