Harry has killed voldermort, only to kill himself also. Ginny and Hermione cannot handle this as their life's fall apart. Draco is now inlove with Ginny and Ron inlove with Hermione, but the two girls dont want that. They are still too sad to love anyone else. Then darkness strikes and the four (Ron, Draco, Hermione and Ginny) find themselves stuck in #12 all alone, locked up in a big house...with only themseves and the ghosts to keep them company.
