The stories are set in two quite distinct societies. Brindabella is a Janeite community that, with minimal help from modern technologies, has recreated the world of Jane Austen in the Brindabella valley of New South Wales. In contrast, Arkadel – a small floating city in the centre of the Pacific Ocean – is one of the most future oriented societies of the time. It is a swarm hive that's inhabitants devote their lives to preparing their Personal Archives to command spindles – tiny space craft designed to explore the galaxy in large swarms, and sow the seeds of settlement.
