Hell Is Empty

An underground vampire club was the last place Hermione Granger expected to find herself. Tasked with questioning elusive vampire king, Mister El, on a string of murders plaguing Wizarding Europe, Hermione discovers she's bitten off more than she can chew. Things get heated when she runs into her ex-lover-turned-vampire, Severus Snape, and he and "Mister El" educate Hermione on the salacious sins of nocturnal life.
