Today was World Book Day and my favourite books are the Harry Potter series. The best book that I think that came out of the Harry Potter series is the Half-Blood Prince....

Read the official blurb below by JK Rowling - I'm sure you will want to read the book afterwards.

There it was , hanging in the sky above the school : the blazing green skull with a serpent tongue , the mark Death Eaters left behind whenever they entered a building ... wherever they had murdered ...

When Dumbledore arrives at Privet drive one summer night to collect Harry Potter , his wand hand is blackened and shrivelled , but he does not reveal why. Secrets and suspicion are spreading throughout the wizarding world , and Hogwarts itself is not safe. Harry is convinced that Malfoy bears the Dark Mark : there is a Death Eater amongst them . Harry will need powerful magic and true friends as he explores Voldermort's darkest secrets , and Dumbledore prepares him to face his destiny.
