Isabelle Duff is a farmer, author, and soon-to-be student at the University of New South Wales, where she will study Advanced Science and Commerce. She is currently on a gap year, working full time on her family farm near Manildra, NSW, where they farm sheep and cattle, and crop. Isabelle is a self-proclaimed "absolute tree hugger," passionate about science and environmental agribusiness. She hopes to one day manage the family business. Cookie is Isabelle’s first book, written when she was just 19 years old. She has volunteered at her local primary school for the past year and a half, and is passionate about opening conversations about mental illness with children at a young age, helping to reduce stigmatism and ignorance. Isabelle’s favourite things in the world are rock music, picnics, Aussie wildflowers and of course, Saffy – her dog (and best friend) who inspired Cookie. She feels more at home in the bush with her beautiful dog than anywhere else.
