A Discovery of Witches by Deborah Harkness. If you like Twilight you might like this. A witch is being hunted by vampires, daemons, humans, and her own kind because of a missing book. This book takes you into the hunt and the love affair between a witch and vampire. The story draws you in and before you know it, the book is finished.
The Witches by Roald Dahl. Roald Dahl played a major part in my childhood, and The Witches was one of my favourites by him. It scared me, and I appreciated having a children's book that didn't flinch from fear!
