In Harry Potter and the Sorcerer's Stone, Harry, an orphan, lives with the Dursleys, his horrible aunt and uncle, and their abominable son, Dudley. One day just before his eleventh birthday, an owl tries to deliver a mysterious letter—the first of a sequence of events that end in Harry meeting a giant man named Hagrid. Hagrid explains Harry's history to him: When he was a baby, the Dark wizard, Lord Voldemort, attacked and killed his parents in an attempt to kill Harry; but the only mark on Harry was a mysterious lightning-bolt scar on his forehead. Now he has been invited to attend Hogwarts School of Witchcraft and Wizardry, where the headmaster is the great wizard Albus Dumbledore. Harry visits Diagon Alley to get his school supplies, especially his very own wand. To get to school, he takes the Hogwarts Express from platform nine and three-quarters at King's Cross Station. On the train, he meets two fellow students who will become his closest friends...
