Harry Potter and the Philosopher's Stone (Harry Potter #1)

Just before the start of the novel, Voldemort, the most powerful Dark wizard in history, killed Harry's parents but mysteriously vanished after trying to kill Harry. While the wizarding world is celebrating Voldemort's downfall, Professor Dumbledore, Professor McGonagall and Hagrid place the one year-old orphan in the care of his Muggle (non-wizard) aunt and uncle, Vernon and Petunia Dursley.
For ten years, they and their son Dudley bully Harry. Shortly before Harry's eleventh birthday, a series of letters addressed to Harry arrive, but Vernon destroys them before Harry can read them. To get away from the letters, Vernon takes the family to a lonely island. As they are settling in, Hagrid bursts through the door to tell Harry what the Dursleys have kept him from finding out: Harry is a wizard and has been accepted at Hogwarts...
