Description: Something sinister stirs in Hogwarts!
When magical creatures and students at the school are hit with a debilitating blood curse, Minerva McGonagall approaches the Ministry for help.
Star Auror Harry Potter seems to be the obvious choice to go undercover—as DADA Professor, naturally. He's going to need the help of the Ministry's foremost expert in blood magic to get to the bottom of the mystery, though, and he's not entirely convinced that going back to Hogwarts with Draco Malfoy is a good idea.
Things are complicated between them—what's new?—but they know they have to learn to work together (and keep their hands off each other in the corridors) in order to solve this case. Luckily for them, Hogwarts itself wants to lend a hand.
A tale of love, lessons, and learning to really live.
