The Defense Against the Dark (and the Dull) (слэш)

In the hallowed halls of Hogwarts, Professors Harry Potter and Severus Snape navigate their first married Christmas as colleagues. Between "borrowed" potion ingredients and faculty-room teasing from McGonagall and Flitwick, the two men prove that love is the strongest magic of all. With Harry as the charismatic DADA professor and a mellowed, yet still sharply witty Severus as the Potions Master, this is a holiday filled with roast turkey, sarcastic gifts, and a deep, quiet devotion that even a Potion Master can't deny.
