The All Souls Trilogy by Deborah Harkness

• 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.
