April 2050. On the remote shores of Phillips Cay, the dream of a sustainable future is nearing its breaking point.

Under the shadow of global tech giant Allied Answers, Methuen Pryce is engineering a blueprint for the Hub Commonwealth - a new sovereign entity. But as Methuen asserts control with the help of Katharina, a cutting-edge AI module, a catastrophic event in North America severs their lifeline and sparks discontent on Phillips.

Suddenly isolated and facing a local mutiny, Methuen gambles everything on a desperate expedition to the neighbouring island of Main. What he finds in the wilderness doesn't just change the plan - it transforms the Hub Commonwealth from a corporate vision into a startling, inevitable reality.

Beyond Phillips Cay is the thrilling third instalment in Francis Nash's Segmented World series of books following on from The Path to Phillips Cay and On Phillips Cay.
