I would like to talk about Harry Potter and the Prisoner of Azkaban, the third novel in the Harry Potter series. It was written by an English writer, J.K. Rowling. I think the genre of this book is fantasy, it is set in an imaginary 'parallel universe' where wizards and witches live their lives in secret, hidden from ordinary people, called the muggles.

The main character of the book is Harry Potter, a young wizard whose life took an unexpected turn when he was invited to Hogwarts School of Witchraft and Wizardy.

In the third book, Harry is in his third year at Hogwarts. Harry and his best friends, Hermione and Ron investigate Sirius Black, who is believed to have betrayed Harry's parents, which lead to their deaths when Harrry was only one year old. Sirius Black escaped from the Prison of Azkaban at the beginning of the book and is thought to be looking for Harry (with the obvious intention of killing him). The plot is quite complicated, there are quite a few mind bending twists. At the end of the novel we learn that Sirius Black was not the villain, he did not betray the parents and did not intend to kill Harry either.

I was really impressed by this book and the brilliant style of the writer. The characters are very interesting - especially the magical creatures, like Buckbeak, the hippogriff or the dementors. I recommend this book to everybody who likes fantasy.
