Drawn to each other despite long-standing taboos, these two otherwordly 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, time 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.

• A Discovery of Witches

• Shadow of Night

• The Book of Life

Deep in the stacks of Oxford’s Bodleian Library, young scholar Diana Bishop unwittingly calls up a bewitched alchemical manuscript in the course of her research. Descended from an old and distinguished line of witches, Diana wants nothing to do with sorcery; so after a furtive glance and a few notes, she banishes the book to the stacks. But her discovery sets a fantastical underworld stirring, and a horde of daemons, witches, and vampires soon descends upon the library. Diana has stumbled upon a coveted treasure lost for centuries - and she is the only creature who can break its spell.

Diana is a bold heroine who meets her equal in vampire geneticist Matthew Clairmont, and gradually warms up to him as their alliance deepens into an intimacy that violates age-old taboos.
