The gate was never meant to be found again.

Captain Julian Harrow and the crew of the survey vessel ISS Meridian are used to danger. Pirate ambushes, abandoned outposts, hostile moons, and the unforgiving dark between worlds come with the job. Yet when a strange signal buried beneath Phobos leads to the discovery of an ancient alien machine, Harrow realises the Solar System is hiding something far older-and far more dangerous-than anyone ever imagined.

Across ten thrilling adventures, the Meridian is drawn into a growing mystery that spans the planets: a drowned city beneath Europa's ice, a ghost fleet trapped in Saturn's rings, a factory hidden in Jupiter's storms, and a buried lock beneath Titan's frozen crust. Each discovery reveals another piece of a lost network left behind by a vanished civilisation.

Harrow is not the only one searching.

From beyond the outer planets, the ruthless Kethari Dominion is moving in silence, reclaiming ancient pathways and hunting the scattered keys to a hidden gate between Mars and Phobos-a gate that could open the Solar System to invasion.

With the reckless Vantari Free Raiders always circling for profit, old secrets buried beneath sealed Survey files, and time running short, Harrow and his crew must stay one step ahead of an enemy that learns, adapts, and never stops coming.

Because if the gate opens, humanity will not be exploring the stars.

It will be defending them.

A fast-paced retro-inspired space adventure packed with alien ruins, pirate battles, strange worlds, hidden machines, and high-stakes pulp heroism, Meridian and the Outer Worlds is perfect for readers who love classic British sci-fi adventure with a modern, cinematic edge.
