一岁的哈利・波特失去父母后，神秘地出现在姨父姨妈家的门前。哈利在姨父家饱受欺凌，度过十年极其痛苦的日子。姨父和姨妈好似凶神恶煞，他们那混世魔王儿子达力――一个肥胖、娇惯、欺负人的大块头，更是经常对哈利拳脚相加。哈利的“房间”是位于楼梯口的一个又暗又小的碗橱。十年来，从来没有人为他过过生日。
但是在他十一岁生日那天，一切都发生了变化，信使猫头鹰带来了一封神秘的信：邀请哈利去一个他――以及所有读到哈利故事的人――会觉得永远难忘的、不可思议的地方――霍格沃茨魔法学校。
在魔法学校，哈利不仅找着了朋友、学会了空中飞行，骑着一把型号为光轮2000的飞天扫帚打魁地球，还得到了一件隐形衣。他发现那里的一切――从上课到吃饭到睡觉都充满了魔力，但是一块魔石出现了，它与哈利的命运息息相关……

As Lord Voldemort tightens his grip on both the Muggle and wizarding worlds, Hogwarts is no longer a safe haven. Harry suspects perils may even lie within the castle, but Dumbledore is more intent upon preparing him for the final battle fast approaching. Together they work to find the key to unlock Voldemorts defenses and to this end, Dumbledore recruits his old friend and colleague Horace Slughorn, whom he believes holds crucial information. Even as the decisive showdown looms, romance blossoms for Harry, Ron, Hermione and their classmates. Love is in the air, but danger lies ahead and Hogwarts may never be the same again.

Harry Potter has lived under the stairs at his aunt and uncle's house his whole life. But on his 11th birthday, he learns he's a powerful wizard—with a place waiting for him at the Hogwarts School of Witchcraft and Wizardry. As he learns to harness his newfound powers with the help of the school's kindly headmaster, Harry uncovers the truth about his parents' deaths—and about the villain who's to blame.

Harry, Ron and Hermione walk away from their last year at Hogwarts to find and destroy the remaining Horcruxes, putting an end to Voldemort's bid for immortality. But with Harry's beloved Dumbledore dead and Voldemort's unscrupulous Death Eaters on the loose, the world is more dangerous than ever.
