As Harry Potter begins his 6th year at Hogwarts School of Witchcraft and Wizardry, he discovers an old book marked mysteriously “This book is the property of the Half-Blood Prince” and begins to learn more about Lord Voldemort’s dark past.

This is the story of Anna Leonowens, the English schoolteacher who came to Siam in the 1860s to teach the children of King Mongkut. She becomes involved in his affairs, from the tragic plight of a young concubine to trying to forge an alliance with Britain to a war with Burma that is orchestrated by Britain. In the meantime, a subtle romance develops between them.

The four-inch-tall Clock family secretly share a house with the normal-sized Lender family, “borrowing” such items as thread, safety pins, batteries and scraps of food. However, their peaceful co-existence is disturbed when evil lawyer Ocious P. Potter steals the will granting title to the house, which he plans to demolish in order to build apartments. The Lenders are forced to move, and the Clocks face the risk of being exposed to the normal-sized world.

Harry’s fourth summer and the following year at Hogwarts are marked by the Quidditch World Cup and the Triwizard Tournament, in which student representatives from three different wizarding schools compete in a series of increasingly challenging contests. However, Voldemort’s Death Eaters are gaining strength and even creating the Dark Mark giving evidence that the Dark Lord is ready to rise again. In the unsuspecting lives of the young wizard and witches at Hogwarts the competitors are selected by the goblet of fire, which this year makes a very surprising announcement: Hogwarts will have two representatives in the tournament, including Harry Potter! Will Harry be able to rise to the challenge for the Tri Wizard Tournament while keeping up with school or will the challenges along with Voldemort’s rebirth be too much for the young hero?
