Harry Potter and the Order of the Phoenix

The 5th book in the Harry Potter series and the halfway point to the finale, aka the 7th book.
After winning the Triwizard cup Harry is a glum Gary because of Cedric's death in the 4th book. Now he’s at the playground sadly swinging on the swing and then he sees his cousin Dudley, they get attacked by dementors (guards of Azkaban prison). Harry fends them off with EXPECTO PATRONUM but, gets in trouble with the ministry of magic for using magic in front of a muggle (non-magical folk). Ultimately, Harry gets exonerated and returns to Hogwarts.
Here's a list of things that happen back at Hogwarts and/or not at Hogwarts:
1 Snape teaches Harry occlumency to keep Voldemort out of his mind.
2 Harry has a dream that Ron’s dad Arthur is attacked by ‘he who shall not be named’ snake Nagini, the attack occurred IRL.
3 Harry has a vision of ‘he who shall not be named’ torturing Snape.
4 Delores Umbridge (the new defence against the dark arts teacher) provokes the centaurs of the Forbidden Forest and is taken away, she shows up later in the series though.
5 Harry and his friends fight ‘he who shall not be named’s death eaters in the ministry of magic.
6 Sirius is killed by Bellatrix Lestrange one of ‘he who shall not be named’s death eaters
7 The ministry of magic see ‘he who shall not be named’ and exclaim that HE’S BACK!
8 Harry goes back to the Dursleys to spend the summer.
I give Harry Potter and the Order of the Phoenix- 5 prophecies out of 5 crystal balls. We’re near the home stretch now, time to see Dumbledore take the tumble to his doom in the 6th book Harry Potter and the Half-Blood Prince.
