I want to buy a book as a Christmas present for a friend but I have no idea what to get, so I'm hoping you guys can help me out with some recommendations. She's 35 years old but she loves reading YA. She's into supernatural stuff like vampires, and the Twilight saga is one of her favourites. I know she also liked A Discovery of Witches by Deborah Harkness. Last year I gave her Daughter of Smoke and Bone by Laini Taylor and while I'm not sure if she's actually read it yet, she seemed excited about it.
Can you think of a book she might like? All suggestions are more than welcome! :)
