Harry Potter and the Sorcerer's Stone by J.K. Rowling

Harry Potter and the Sorcerer's Stone is the first in the famous series by author J.K. Rowling. In it, young Harry Potter is living with the Dursley family, his Aunt Petunia, Uncle Vernon, and cousin Dudley. And it's hard to imagine a family who could treat him worse. The Dursleys are awful to Harry, making him live in the storage area under the stairs instead of a proper room, and speaking to and treating him horribly. But then one day, a mysterious letter comes for Harry, which his aunt and uncle are strangely insistent he not read. After trying to evade the sender of the letter (and many more that come to replace the first after Uncle Vernon and Aunt Petunia destroy it) a giant of a man confronts the family, and delivers a message that shocks Harry to his core. "You're a wizard, Harry." After this, an adventure he never expected, begins!
