Discovery of Witches, A
Twilight meets The Historian. The protagonist is a witch, but vampires figure prominently. Diana Bishop is a renowned scholar on alchemy doing research at the Bodleian Library at Oxford. She pages an enchanted book and all hell breaks loose in the creature community (which includes daemons as well as witches and vampires). The research part is interesting, but the story devolves into the overprotective male vamp, gendered power struggle, and abstinence porn that drove some feminists crazy about the Twilight series.
