For me, chapter 4 of book 7 - The Seven Potters - will always be one that I will enjoy from start to finish. Starting with the way six other characters were each transformed into a 'specky git' aka Harry, I remember having so much fun using my imagination to picture seven identical persons in the room, who all brought Harry to 'life' in a different ways in terms of mannerisms.
Then came the battle after they departed from Privet Drive. That was quite chaotic with so much happening, yet it was super easy to picture. Each spell cast, each reaction by the characters, the suspense of wanting the good guys to make it out alive… it was all mindblowing.
Yep. That’s definitely my chapter
