I have always enjoyed books about vampires, witches and the like long before they became popular from books like Twilight etc. I had first read about this book in my Entertainment Weekly and I wanted to buy it for quite some time. When I got my Nook I figured it was a great time to try out not hauling around a 500 plus page book with me.
It was a quick read and one I found myself reaching for instead of getting bored. The characters were well developed and the setting was one that was believable besides the fantasy aspect of the book.
Barnesandnoble.com summarizes the book this way:
A richly inventive novel about a centuries-old vampire, a spellbound witch, and the mysterious manuscript that draws them together.
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.
