She has crafted a marvelous story about a young New Zealand girl trying to solve the mystery of why her mother ran away when she was a small child. So how did Susan get to write so beautifully? Our guest critic intends to find out: Alan Ventress, who worked for 8 years as head of Sydney's prestigious Mitchell Library.
