One year after the Final Battle, Hermione Granger has returned to Hogwarts alone. She finds herself relating the most to the least-likely person she ever imagined—Draco Malfoy. Then, five years after the Battle of Hogwarts, Draco Malfoy is working at Gringotts Bank. An unlikely expedition has him growing close once again to the most enigmatic witch of his past—Hermione Granger.

Merlin's law dictates anything that can go wrong, will. The war is over and McGonagall feels it's time that something is done about the breach between wizards and muggles. What better way to mend that union than to send her returning seventh years into the muggle world for the semester.
