A Discovery of Witches — Deborah Harkness

Deep in the heart of Oxford'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 descends upon the library. Among them is the enigmatic Matthew Clairmont, a vampire with a keen interest in the book. Equal parts history and magic, romance and suspense, A Discovery of Witches is a mesmerizing and addictive tale of passion and obsession that reveals the closely guarded secrets of an enchanted world.
