Brimming with rich detail and humour that perfectly complements J.K. Rowling's timeless classic, Jim Kay's glorious illustrations will captivate fans and new readers alike. When a letter arrives for unhappy but ordinary Harry Potter, a decade-old secret is revealed to him that apparently he's the last to know. His parents were wizards, killed by a Dark Lord's curse when Harry was just a baby, and which he somehow survived. Leaving his unsympathetic aunt and uncle for Hogwarts School of Witchcraft and Wizardry, Harry stumbles upon a sinister mystery when he finds a three-headed dog guarding a room on the third floor. Then he hears of a missing stone with astonishing powers, which could be valuable, dangerous - or both. An incredible adventure is about to begin!
