Hogwarts Homecoming

Hermione Granger takes the risk of becoming the Defence Against the Dark Arts at Hogwarts after the war. Little does she know that another ex-pupil has also been recruited to teach the young students. Will Hermione's position of power and urge to be young and let loose get the better of her? Or is there more to it? DM/HG. Rated M. Reader discretion is advised.
