A Discovery of Witches - Deborah Harkness This book was so engrossing, I literally felt as thought I was in story with Diana and Matthew! The amazing detail of the alchemic process and imagery was amazing. This author did her homework! This love story touched me and left me longing to see what happens next! Vampires, witches, demons and humans and the story of their existence, from creation to evolution...what an great concept!
