Harry Potter and the Heir of Black (HP8)

Things have changed since Voldemort's defeat. Harry and Ron have gone out to work, and Hermione is on her way back to Hogwarts for her final year of education. However, little does she realise that this year will be just as eventful as the last seven. She also doesn't realise that while on the Hogwarts Express with Ginny and Luna, she will meet a young man who isn't what he seems.
