The Blackbird Oracle
Diana Bishop journeys to the darkest places within herself—and her family history—in the highly anticipated fifth novel of the beloved #1 New York Times bestselling All Souls series.
Deborah Harkness first introduced the world to Diana Bishop, Oxford scholar and witch, and vampire geneticist Matthew de Clairmont in A Discovery of Witches. Drawn to each other despite long-standing taboos, these two otherworldly beings found themselves at the center of a battle for a lost, enchanted manuscript known as Ashmole 782. Since then, they have fallen in love, traveled to Elizabethan England, dissolved the Covenant between the three species, and awoken the dark powers within Diana’s family line.
Now, Diana and Matthew receive a formal demand from the Congregation: They must test the magic of their seven-year-old twins, Pip and Rebecca. Concerned with their safety and desperate to avoid the same fate that led her parents to spellbind her, Diana decides to forge a different path for her family’s future and answers a message from a great-aunt she never knew existed, Gwyneth Proctor, whose invitation simply reads: It’s time you came home, Diana.
On the hallowed ground of Ravenswood, the Proctor family home, and under the tutelage of Gwyneth, a talented witch grounded in higher magic, a new era begins for Diana: a confrontation with her family’s dark past, and a reckoning for her own desire for even greater power—if she can let go, finally, of her fear of wielding it.

Deborah Harkness
Before Deborah Harkness ever wrote about witches, vampires, or daemons, she was chasing ghosts of a different kind—lost manuscripts, forgotten alchemists, and the hidden truths of Renaissance science. A historian by trade, she spent years immersed in the dusty corridors of academia, unraveling the ways magic and science once danced hand in hand. That lifelong fascination became the lifeblood of her fiction.
When A Discovery of Witches appeared, it wasn’t just another entry into the paranormal genre—it was something richer. Woven with real history, wine-soaked libraries, and the quiet ache of forbidden love, the story offered readers a deeper, more thoughtful kind of fantasy. At the center of it all stood Diana Bishop, a scholar who stumbles across a bewitched manuscript and is forced to confront a world she’s spent her life trying to ignore.
