Joanne van Os grew up in Melbourne, eldest of six children. After working as a laboratory technician in marine pollution studies, she moved to the Northern Territory to be the radio operator at a remote Aboriginal community. Since then her jobs have included bull catcher, buffalo station owner, home schooling teacher, electorate officer for an Independent MP, boat hire business owner/operator, cartoonist, and mother of three children.

Her first book, memoir Outback Heart, was published in 2005, and followed by children’s novels Brumby Plains, Castaway, and The Secret of the Lonely Isles. Ronan’s Echo (2014) is her fifth book, and first adult novel.

She is currently sailing from Darwin down the east coast of Australia with her husband Lex Silvester on their yacht Tramontana, and working on a new novel when the table stays level.
