I've read this book more than 18 years ago, so I won't be able to pinpoint all the details. We've just watched the movie version of this piece last night, and my youngest son just couldn't help but complain about how different the movie is from what's really written. I couldn't blame him, but our movie session still went through for the gazillionth time.
The Triwizard Tournament, Professor Moody, Rita Skitter, the Minister of Magic himself, and all graced this piece. Love angles and friend squabbles also added twists and turns. The ending had been heartbreaking, and yet the story continues on so there was still hope. I really looked forward to Book 5 thereafter.
