Isobelle began the first of her highly acclaimed Obernewtyn Chronicles while she was still at high school and worked on it while completing a Bachelor of Arts and then a journalism cadetship. The first book was accepted by the first publisher she sent it to and went on to be short-listed in the Older Readers section of the Children’s Book Council Book of the Year Award for older readers. The series and her short stories have established her at the forefront of fantasy writing in Australia.
Isobelle is currently working on The Red Queen, the final book in the Obernewtyn Chronicles, and the screenplay for Greylands, on a Film Australia grant. She has also begun a PhD at the University of Queensland.
