I got to read Chamber of Secrets as one of my class books in primary school and remember how freaky I found it! I also was terrified by the opening of Goblet of Fire - the story of them finding the dead Riddles.Currently watching Harry potter and the chamber of secrets, which is also my fave book from the series .I still remember being 10 years old and reading it alone at night and actually feeling scared when it said "the chamber of secrets has been opened". Can't get back that feeling of reading it for the first time.
I bought the last few books at midnight sales too and literally didnt sleep til the morning I was so engrossed. I love thinking about that excitement.
