In this book, Harry Potter is visited by a group of wizards and then goes to Sirius Black’s house, which serves as the headquarters of the Order of the Phoenix. The Order of the Phoenix is a group of wizards led by Hogwarts headmaster Dumbledore. Their mission is to prevent Voldemort from rising to power again. However, they must operate secretly to avoid detection by the Ministry of Magic.
This book, like its predecessors, was enjoyable. The scenes are vividly written, and the world is depicted as strict and firm. It's a beautiful and emotional book. However, this book is the longest in the series at 870 pages. Because of its length and the slow start to the main action, it became boring and difficult to read.
