Spellbinding Encounter (слэш)

In the course of her job, while reading through an ancient spell book, Hermione accidentally brought Snape back from the dead, but she wasn't even thinking about Snape at the time. Severus eventually recovers, and is given an Order of Merlin first class for his sacrifices made during the war. He returns to Hogwarts to teach potions again, while Harry plans to teach DADA as soon as he passes his teaching exams. Somehow, Snape and Harry's Patronuses keep meeting in the middle of the night and have sex with each other.
