Before the start of the novel, Voldemort, considered the most evil and powerful dark wizard in history, kills Harry's parents but mysteriously vanishes after trying to kill the infant Harry. While the wizarding world celebrates Voldemort's downfall, Professor Dumbledore, Professor McGonagall and Rubeus Hagrid place the one year-old orphan in the care of his neglectful and abusive Muggle (non-wizard) uncle and aunt: Vernon and Petunia Dursley, who have a son, Dudley, a spoiled and selfish boy.For ten years, Harry is tormented by the Dursleys. Shortly before his eleventh birthday, a series of letters addressed to Harry arrive, but Vernon destroys them before Harry can read them, leading only to an influx of more letters. To get away from the letters, Vernon takes the family to a small island. As they are settling in, Hagrid bursts through the door to tell Harry what the Dursleys have kept from him: Harry is a wizard and has been accepted at Hogwarts.
