If she'd spent another ten chapters tidying everything up, Return of the King style, the book would have been too heavy to lift without a winch!
Also, I wonder why none of the other wizards throughout the world never came to the aid of the British wizards after Voldemort and the Death Eaters had taken over? For example, the wizards and witches from Beauxbatons in France?
Kind of makes the whole Tri Wizard tournament seem pointless doesn't it? Isn't the whole point of the Tri Wizard tournament supposed to be "international magical cooperation"?
I guess the next Tri Wizard tournament will be somewhat strained, with all the Hogwarts students and faculty saying to the other schools, "thanks for nothing with that whole Voldemort war, as$holes!"
