Harry Potter y la Piedra Filosofal (Harry Potter and the Sorcerer's Stone)

Harry Potter #1

When mysterious letters start arriving on his doorstep, Harry Potter has never heard of Hogwarts School of Witchcraft and Wizardry.

They are swiftly confiscated by his aunt and uncle.

Then, on Harry’s eleventh birthday, a strange man bursts in with some important news: Harry Potter is a wizard and has been awarded a place to study at Hogwarts.

And so the first of the Harry Potter adventures is set to begin. ([source][1])
