Fra forlagets omtale: 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.
