What a fun read! A witch and a vampire meet and fall in love, even though it's forbidden. Their common search for a lost, secret manuscript creates all sorts of challenges. To complicate things further, Diana, the witch, has actively avoided magic her whole life, which means she's just now learning how to use her power. One of the best things about this story is that it is book one of a trilogy!
Discovering a magical manuscript in Oxford's library, scholar Diana Bishop, a descendant of witches who has rejected her heritage, inadvertently unleashes a fantastical underworld of daemons, witches, and vampires whose activities center around an enchanted treasure.
