Books I Should Have Already Read, Harry Potter and the Prisoner of Azkaban

Keeping on keeping on. This copy I got for free on my wife's neighborhood freecycle page. I mean the front cover was ripped off but the rest of the book was there!

• These book covers (and I know there are more) always show Harry and the crew in like normal clothes. he is wearing jeans. But the books always talk about robes and I imagine these guys running around in muu-muus with maybe some underpants and a tshirt underneath. 
• I have only read three of these books but this one is my favorite so far. There is enough of a familiarity with the characters and setting to feel comfortable but she opens up more of the world. Harry "blowing up" Aunt Marge, the trips to other places in the magical Hogwarts world, the Quidditch final, Snape finally losing his utter shit at Harry, etc all feel very organic, necessary, and rewarding. Do they go downhill from here?!
• Ron is still my homebody and there is a very uncomfortable and sudden bit of violence that describes how his leg breaks as he gets sucked under the Whomping Willow near the book's climax.
• Speaking of climax, when I read the first part of it I was a bit frustrated. Here is Harry getting deus ex machina'ed AGAIN but its actually a clever trick as his FUTURE self is the one who fires the Patronus spell.
• Dementors sound very cool and creepy AND I know 100% get the Prison Mike reference of The Office what with "The toughest part of prison was the dementors" joke. I want to visit Azkaban. I imagine it as basalt cone volcano rising from the sea and encircled by a island high chain of stone steps. Then hundreds of cell facing out from the rock into the sea at the steps with metal bars over their openings. The dementors loop endlessly on the stairs like video game guards for eternity.
• I ALSO got a Twitter joke where a user, in reference to the high turnover of officials in the Trump administration (Only hire best people you know) said "Hogwarts loses another Defense Against the Dark Arts teacher" What a lovely cosmic coincidence.
• Doesn't the presence of a Defense Against the Dark Arts imply and welcome a looming and potential violence? Magical Self Defense perhaps because can't even your best bud totally clobber you with some bolt of purity or what not?
• I still know nothing about Ravenclaw or Hufflepuff save Hufflepuff wears canary yellow.

On to the next book!
