As soon as you start reading A Discover of Witches, you understand why it was an Amazon book of the month and has been so highly reviewed. Deborah Harkness, a history professor at USC, is a talented writer. The premise of the book twists the witch/vampire genre lending both history and science to the story. Diana Bishop, the main character, is descended from Bridget Bishop, executed during the Salem Witchcraft Trials. She meets Matthew Clairmont, a vampire, after requesting Ashmole 782 from the stacks at the Bodleian Library at Oxford. This text which has been lost for many years brings representatives from all three creature races, witches, vampires, and daemons, and all three have different ideas about what is contained in the book.
I highly recommend this book. The story flows wonderfully, and as a history buff, I really enjoyed the tidbits of history scattered throughout. Harkness is a master of character development and of description. My only problem is that it is the first book in a trilogy!
