Umbridge was in her office when all of a sudden 5 books appeared on her desk when she saw the title of the first book she thought all her dreams had come true at once. So she ran down to the great hall calling all staff and students there so she could finally reveal what a liar Harry James Potter is.
All staff and students are in the hall and umbridge decides to call in a few people from the ministry to sit and listen to the books, so kinglsley, amelia bones, alistair moody and fudge all showed up. Dumbledore asks why they all have been gathered in the hall so umbridge stands up and says i was in my office when 5 books appeared detailing the life of harry potter while sayin that she gives a nasty grin to harry who looks like he wants the floor to swallow him up, so dumbledore asks if its ok for him to invite a few people of his own to read the bokks so she says its fine a few minutes later walking into the great hall is Molly and Arthur Weasly, Remus Lupin, Tonks and Sirius in dog form.
So while they all are getting settled down harry goes and sits with remus and sirius knowing they are not going to like whas going on in the books.
Umbrige says she will read first.
