Hermione Granger, well, sorry, Deputy Headmistress Hermione Granger, has picked up the pieces after the Second Wizarding War and established herself as a respected faculty member at Hogwarts. But that doesn't mean that the world didn't come out of the War unscathed. A strange virus was released by the Death Eaters just before they were captured that is leading to declining magical abilities of witches and wizards and its gradually getting worse. Hermione was tasked with running a lab to determine the cause and cure for the virus, but is struggling with limited Ministry funding and resources. That is, until a former Death Eater, who now sits in Azkaban, is given to her as a lab assistant since he might have information about the virus-he was, after all, there when it was created. Court ordered to her lab against her wishes, Draco Malfoy and Hermione must try to work together. But it's not that simple. In fact, everything they thought they knew about each other becomes even more complicated than they could have imagined.
