Earth is dying. Humanity knows it, and humanity does not care enough to stop.

In a future scarred by environmental collapse, overconsumption, and political paralysis, former RAF Group Captain James Kidd is drawn into a last-ditch survival programme: the construction of vast space habitats in the Asteroid Belt, designed to preserve human civilisation when Earth can no longer sustain it.

But the mission changes everything.

A mutated virus grants James and a handful of others dramatically extended lifespans, transforming them from soldiers into centuries-old witnesses to humanity's darkest era and its most extraordinary recovery. When an alien vessel arrives in the outer solar system, first contact brings not invasion but an uneasy, transformative alliance that will propel James and his crew beyond the Milky Way and into the Andromeda Galaxy.

Told by James himself, dictating his life story as his lander spirals toward a crash on an alien world, H1 L1 A0 is a sweeping hard science fiction novel that spans five hundred years, four extraordinary lives, and the question that defines them all: when Earth wasn't enough, what did we become?

The first instalment in a planned twelve-novel series, H1 L1 A0 combines rigorous scientific world-building with a deeply personal story of love, loss, and survival across the centuries.
