"I don't think I had ever felt so excited. I thought, 'I'd love to write that,'" she says. "I'd never thought about writing for children—I'd never thought about aiming anything at that age group. And yet it was the thing that I was meant to write."
In Harry Potter and the Sorcerer's Stone, Jo first introduced the world to Harry Potter—a boy who appears perfectly ordinary to "Muggles" (non-magic people). However, in the wizarding world, he's a legend. Harry spends the first 11 years of his life living with his dreadful Muggle aunt and uncle, completely unaware that he's a wizard and that there's an extraordinary destiny awaiting him. As the story says, "One day, every child in the world will know his name."
While there was no way Jo could have predicted that every child in the world would one day know her name as well, she said she did have an epiphany while writing the first Harry Potter book.
"I had this moment where I suddenly thought—it was like another voice speaking to me—and the voice said: 'The difficult thing is going to be to get published. If it's published, it will be huge,'" she says. "And that is exactly what it was."
