A graduate of Exeter University, a teacher, and then an unemployed single parent, Rowling wrote Harry Potter when "I was very low, and I had to achieve something. Without the challenge, I would have gone stark raving mad." But Rowling has always written; her first book was called "Rabbit." "I was about six, and I haven't stopped scribbling since."

For Rowling, the change in her fortunes has been slightly bewildering. But her daughter has no doubt about her mother's new career: when asked what mommies do, she replies without hesitation, "Mommies write!"
