"I get the most satisfaction from seeing someone who first came to Kumon struggling with maths develop into a capable mathematician with the confidence and study skills to tackle any problem."
I loved this book, I thought it followed up from 'The Goblet of Fire' really well. It wasn't better than my favourite Harry Potter so far though, which is 'Prisoner of Azkaban'. People that haven't read the other Harry Potter books won't enjoy it as much as people that have as they won't know the characters as well.
It is a very long book and takes a long time to get into Hogwarts which I don't think is a good thing but once the story began properly I found it hard to put it down! Professor Umbridge is a really nasty character, somebody everyone loves to hate. You see a lot more of Ginny in this book as well which is really good (I think she will become a more important character in the next two books). You find out more about Harry, Ron and Hermione's other friends like Cho Chang and Neville and this makes the book interesting.
The best bit of the book for me is towards the end and is 'the prediction'. It links into the previous books really well and explains a lot that JK Rowling had left unexplained.
