The war against Voldemort is not going well; even the Muggles have been affected. Dumbledore is absent from Hogwarts for long stretches of time, and the Order of the Phoenix has already suffered losses.

And yet . . . as with all wars, life goes on. Sixth-year students learn to Apparate. Teenagers flirt and fight and fall in love. Harry receives some extraordinary help in Potions from the mysterious Half-Blood Prince. And with Dumbledore's guidance, he seeks out the full, complex story of the boy who became Lord Voldemort -- and thus finds what may be his only vulnerability.

In case you don't remember, Harry Potter is an eleven year old wizard. Long ago, Harry's parents were killed in a battle with the evil Lord Voldemort. When we first meet Harry, he is living miserably with his repulsive and non-magical (or Muggle) Aunt Petunia and Uncle Vernon and their even more revolting son Dudley. Following a bizarre but hilarious chain of events, Harry finds himself at Hogwarts School of Witchcraft and Wizardry, with an outrageous cast of characters, including super-smart Hermione, vile Draco Malfoy, sinister Professor Snape and the wise Headmaster Albus Dumbledore.
