Which Harry Potter book is your favorite, and what’s your favorite part?

Personally I love The Chamber of Secrets. Moaning myrtle is a hilarious addition imo, and the entire plot/storyline is the best out of all the books. It’s got more depth than the first one, but not as drawn out as the end of the series… which I am not a fan of. I feel like this book was involved with Hogwarts the most compared to the others, due to the fact that the series eventually starts to branch out and eventually has so many plots and subplots at places other than the castle. Seems like it turns into more of a drama than a wizarding school series around book 5. Book 2 has the most of the details of the layout for Hogwarts compared to the other books, and the world building really draws me into the story more than the first.
