Meet J.J. Green

J.J. Green is a British-Australian science fiction author with a lifelong love of distant landscapes, intriguing cultures and fascinating places. She was born within the sound of the bells of Mary-le-Bow church in Cheapside, London, making her a bone fide Cockney, and she lived in Australia, Laos and Taiwan before returning to the UK to settle down in Cambridge.


J. J.’s novels weave science-based speculation with richly personal stories. Her works explore themes of environmental degradation, political conflict, mythical resonance, human resilience, and the ethics of technology and expansion. Her characters—often strong women—navigate future worlds grounded in both scientific plausibility and mythic imagination.
