A Discovery of Witches

A Discovery of Witches by Deborah Harkness

Deep in the heart of Oxfords's Bodleian Library, Diana Bishop, a young scholar and the descendant of Witches,  unearths an enchanted alchemical manuscript. Wanting nothing to do with sorcery, she banishes the book to the stacks.

But her discovery has set a fantastical underworld stirring, and soon a horde of daemons, witches, and other creatures descend upon the library. Among them is the enigmatic Matthew Clairmont, a vampire with a keen interest in the book.

I recommend that you give this novel a chance and follow Diana and Matthew on their adventure through the secrets of an enchanted world.
