This takes place years after the final battle. Harry and the gang have gone back to Hogwarts but this time it's all different. No longer are they the students, learning all they can from great wizards and witches, they are now the professors themselves. It's time for them to control things because you can't have greater teachers than the ones who've lived the history they will soon be teaching. Follow 'the Boy Who Lived' and the rest of the new Hogwarts staff and see where they go. They'll face love, loss, extreme happiness and horrible sorrow. Everything has changed now, the world is theirs.
