"A Discovery of Witches."
It's starting out a little like an adult Twilight, with an Oxford researcher who's also a witch (and trying to hide it) meeting a vampire in the university library. At first she's all angry with him and wishes he were gone, but you can sense a relationship coming.
I'm not the world's biggest "Twilight" fan, though I've read them all. Still, I like the Oxford setting and the plot seems to be going somewhere, so I'm enjoying it quite a bit.
