Harry Potter & The Chamber of Secrets is a continuation of Harry’s journey in the wizardry school of Hogwarts. The book basically starts when messages appear on the wall. These messages say that the "Chamber of Secrets" has been opened and that the "heir of Slytherin" will kill all students who are muggles. These threats are found after attacks on some students that leave everyone in the school scared. Harry starts his own little investigation with his friends, Hermione and Ron.
The book is full of mystery, but it has its share of funny too, like a new professor, Gilroy Lockhart, thinks that he is the best at everything, as he shows off to his students including Harry, Hermione and Ron. Eventually, Professor Lockhart, ends up humiliating himself many many times in front of his pupils.
In another part, Harry and Ron decide to use an enchanted flying car to get to Hogwarts from summer break. Just as they arrive at Hogwarts, the car begins to break down and they end up crashing into a tree that swings its branches wildly. Harry and Ron somehow survive, but eventually get detention.
So, overall, it is a good read, but personally, it is my least favorite book in the series.
