Cloud Permutations

The world of Heven was populated, centuries ago, by Melanesian settlers from distant Earth. It is a peaceful, quiet world – yet it harbours ancient secrets.

Kai just wants to fly. But flying is the one thing forbidden on Heven – a world dominated by the mysterious, ever present clouds in the skies. What do they hide? For Kai, finding the answer might mean his death – but how far will you go to realise your dreams?

Set against the breathtaking vista of a world filled with mystery and magic, Cloud Permutations is a planetary romance with a unique South Pacific flavour, filled with mythic monsters, ancient alien artefacts, floating islands and a quest to find a legendary tower… whatever the cost.


A novella inspired by life in the South Pacific and a love of Cordwainer Smith, written in Vanuatu. Published July 2010 by PS Publishing, in limited edition hardcover format, with cover artwork by Pedro Marques.
