The series has come a long way since then. Now sold to more than twenty countries, the series regularly appears on the New York Times Bestseller List and has been shortlisted in children's book awards in Australia and overseas. John, a former television and advertising writer, lives with his wife, Leonie, in the Sydney beachside suburb of Manly.
