Kathy Lette is a comic writer and pioneering voice in contemporary feminism whose first book, Puberty Blues, was published in 1979. Co-authored with Gabrielle Carey, it catapulted her into the public eye, horrifying her headmistress mother with its graphic depictions of teenage sex and drug taking. She has subsequently written 21 best-selling books and today speaks with The Sydney Morning Herald’s deputy opinion editor, Margot Saville, ahead of the release of her newest novel, The Sisterhood Rules.
