I love this book! I'm re-reading the Harry Potter series, and it's been awesome! It's about Harry's principal, Dumbledore, starts up the Order of the Phoenix, a secret society whose job is to take down Voldemort. While that is happening, Harry, Ron, and Hermione are suffering from a lot of homework and are stuck with Professor Umbridge as a teacher. Then Hermione gets an idea: what if they could make a Defence Against the Dark Arts army, just as the Ministry feared?
