After reading the Harry Potter series for the twentieth time and tackling the Twilight Trilogy over and over, you're still aching for more supernatural? There are thousands of books out there infiltrating the mystical genre, but not all of them will give you the fix you need. Luckily, we've been hearing a ton of buzz about A Discovery of Witches ($15) by Deborah Harkness. The novel is geared toward adult readers and takes place in a world where witches and vampires roam. An all-encompassing love story, with history and myth thrown in, you'll want to read this in one sitting and then promptly start it again.
