I love this book so much! I would give it a 10/10. You get to meet the Order of the Phoenix,, a secret organization founded by Dumbledore, to take down Voldemort. Meanwhile, at Hogwarts, the "old hag", Delores Umbridge, isn't teaching DADA so well. Hermione gets an idea: what if Harry teaches kids DADA himself, and form an "army", or, Dumbledore's Army, just as the Ministry feared?
