Harry enters his sixth year at Hogwarts knowing that he has a pivotal role to play in the now-open war against Voldemort, sure that Draco Malfoy is up to something, and more than a little conflicted by his attraction to Ginny Weasley, sidekick Ron's suddenly not-so-little sister. Harry's relationship to Dumbledore is entering a new phase, too, as under the kindly old wizard's direct guidance, he begins taking trips through a series of magically preserved memories to explore his archenemy's parentage and character.

Meanwhile, Harry's glee at getting a leg up in Potions class thanks to a heavily annotated old textbook that once belonged to a mysterious "Half-Blood Prince" rivals his discomfort at being caught between Ron and Hermione, who are going through a rocky patch, and the horror of discovering that his new Defense Against the Dark Arts instructor is none other than hated, hateful Severus Snape. How could Dumbledore possibly insist, as he repeatedly does, that Snape is a trustworthy ally?

While charting teenage infatuations and friendships with a wry wit that occasionally tumbles into outright merriment, Rowling tucks in several revelations (notably, the secret to Voldemort's seeming immortality), adds a dash of sympathy for Malfoy (of all people!), who does indeed turn out to be part of an ugly scheme, and further develops Snape's role as a pivotal character. Then, after a heartrending test of Harry's loyalty to Dumbledore, Rowling propels the plot to a climax that is-thanks to artful pre-pub preparation-tragic, but not uncomfortably shocking. This newest excursion into the Potterverse will leave readers pleased, amused, excited, scared, infuriated, delighted, sad, surprised, thoughtful-and likely wondering where Voldemort has got to, since he appears only in flashbacks. There's no doubt, however, that he'll figure prominently in what promises to be a spectacular finish.

Gr 5 Up-Opening just a few weeks after the previous book left off, the penultimate entry in the series is, as the author foretold, the darkest and most unsettling yet. The deeds of Voldemort's Death Eaters are spreading even to the Muggle world, which is enshrouded in a mist caused by Dementors draining hope and happiness. Harry, turning 16, leaves for Hogwarts with the promise of private lessons with Dumbledore. No longer a fearful boy living under the stairs, he is clearly a leader and increasingly isolated as rumors spread that he is the "Chosen One," the only individual capable of defeating Voldemort. Two attempts on students' lives, Harry's conviction that Draco Malfoy has become a Death Eater, and Snape's usual slimy behavior add to the increasing tension. Yet through it all, Harry and his friends are typical teens, sharing homework and messy rooms, rushing to classes and sports practices, and flirting. Ron and Hermione realize their attraction, as do Harry and Ginny. Dozens of plot strands are p
