You may know her as Claire North, author of "The First Fifteen Lives of Harry August." You might also know her as Kate Griffin, author of the urban fantasy series about sorcerer Matthew Swift. You may have read her Horatio Lyle detective novels, which she published under her real name, Catherine Webb. But even if you haven't read any of her novels, you're in for a treat. I talk with Catherine Webb about being a wunderkind who got published in high school, and why she might be on the verge of coming up with another pseudonym. Featuring readings by actress Robyn Kerr.
