Harry Potter and the Half-Blood Prince (2009)

Potter encounters a surprise during his 6th year at Hogwarts. Coincidentally, he will start to discover the mystery of the Half-Blood Prince as a result of finding a book that says 'Property of the Half-Blood Prince' on it and tampering with the spells within the book. Although the wise wizard Dumbledore's companionship makes it easier for him to settle accounts with his dark enemy Voldemort, this time Harry Potter and his friends await a very tough battle.
