The fourth book is the turning point in the Harry Potter series, it’s true when the books take a dark turn, and in almost every book after that, there is at least one death since the book is where the dark lord returns with more power than ever but no one believes harry except a few people including Ron, Hermione, and their headmaster.
In the book the dark lord wanted Harry to participate in a tournament that was taking place that year.
In the end, we find out that there was a traitor in Hogwarts who was working with the dark lord and he secretly kept helping harry so in the last round the dark lord can use him to come back but what most surprises the readers is the big twist in the end which none of us expects and throws us quite off the hook.
We also learn that there was a traitor in the school who also helped harry pass through the setup that led to the dark lord’s return.
