Harry Potter — J.K. Rowling

J.K. Rowling's seven-novel series (1997-2007) is the best-selling book series in history with over 600 million copies sold in 80+ languages. More than any other 20th-century fantasy, including The Lord of the Rings, Harry Potter created readers — bringing a generation to books who had not previously been readers and sustaining their engagement through eight years of increasingly sophisticated storytelling about power, prejudice, death, and the courage to resist.
