Harry Potter

My favourite book would have to be the 'Half - Blood Prince. One of my favourite parts is  - Harry finds a potion book with things crossed and corrected, notes on the side of the pages and a mysterious spell 'Sectumsempra' after he starts following the 'Half - Blood Prince's insructions he becomes top of the class which Hemione isn't to happy about and becomes a bit jealous.

I also like it because it shows the relationships between Harry and Ginny and Ron and Hermione.
