Harry Potter and the Prisoner of Azkaban

Voldemort's biggest follower, Sirius Black, has escaped from wizard prison, Azkaban. He was last heard mumbling "He's at Hogwarts," in his sleep, and everyone is afraid he's coming after Harry, who was Voldemort's downfall when Harry was a baby and Voldemort's murderous curse backfired, and instead of killing Harry, Voldemort was reduced to a weakened nothing instead of the powerful dark wizard he was.
I love the Harry Potter series and read this one at least twice personally, so it was fun to read it to the kids. Most people probably like the later books, but this one is my favorite in the series. Every detail in the book ties into a completely unpredictable ending. Nothing is as it seems.
I plan to read the whole series to the older kids and hopefully they will love it as much as I do.
The author who narrates the series on audio CDs is fantastic. I usually will get audios from the library because they're pricey, but this one was worth purchasing. I actually bought it years ago but I pulled it out so the kids could enjoy it in the car since we were reading it at home.
This book is listed as 6th grade level but if you are reading it to them, I think ages 8 and up would enjoy it.
