Kaz Cooke is an Australian author and cartoonist, and former teenage girl. She has a background in journalism and flibbertigibbeting. She is often a columnist; sometimes a radio broadcaster; the bestselling author of Up the Duff, Kidwrangling, The Little Book of Stress and Real Gorgeous; and the winner of the 2002 UK Diagram Prize for the Oddest Title of the Year, Living with Crazy Buttocks. Her books have been translated into many languages: in Latvian she is Keza Kuka and in Czech she is Kaz Cookeova. She has too many handbags and never knows where her mobile phone is.
