Harry Potter and the Sorcerer's Stone is the first book in a seven-part series about the powerful young wizard Harry Potter. In this book, he's orphaned and sent to live with his aunt and uncle. Years later, he receives an acceptance letter from Hogwarts School of Witchcraft and Wizardry, where he will have many dangerous and fantastic adventures.
Hagrid leaves an infant Harry Potter with his aunt and uncle, the Dursleys. There's some mystery surrounding Harry's parents, and it isn't until later that he learns they were killed by Lord Voldemort, an evil Wizard. This attack left Harry with a prominent scar.
Upon acceptance to Hogwarts, Harry discovers that he's one of the most famous people in the wizarding world. He quickly becomes friends with Hermione and Ron and makes an enemy of Draco.
At the end of the school year, Harry comes face to face with Lord Voldemort—what's left of him, anyway. With the help of his friends, Harry manages to defeat Voldemort and the professor who'd been helping him. For the moment, Harry is safe.
