This is my favorite book because it's got a good plot to it and it's the most adventurous book I've ever read. This Harry Potter book is better than the others in the series because the adventures are more exciting, way more scary and keeps you guessing about what will happen next. In the middle of the book you'll find out something suprising about Sirius Black. My favorite character in this book is Sirius Black because he James Potter's (Harry's Dad) friend. He does good things to help Harry.
I recommend this book to people who like books that have wizards, witches and adventures. I also recommend this book to kids age seven and older. I also think this book is good for boys and girls!!! I think people should read the books before they see the movies so that you'll understand the movie better.
