The trilogy · Complete in three volumes

Tapache's Promise Trilogy

Ancient machine intelligences. Resurrected species with no memory of the past. Creatures composed of gravity strings. What is hidden in the void between galaxies?

Echoes of Gravity book cover

Book One

Echoes of Gravity

Was Tapache lying?

Read the blurbClose

Tapache, a machine intelligence with great power, has revived the Roranian people from their derelict remains. It has gifted them the Great Ship to voyage through space and given them a purpose: to discover the truth about a weapon capable of unthinkable devastation.

An unexpected attack, followed by hundreds of years in stasis, scuppers those plans. Hope seems lost for a small group of Roranian survivors, until something far greater draws them in: a megastructure beyond comprehension.

The megastructure is far from safe. There are incumbent species that already lay their claim, all with secrets of their own, and a strangely smart information network that exists where it has no right.

“Part space opera, part political thriller. It's refreshing to read a grand-scale SF epic that doesn't rely on space battles and military tropes. It's really like Banks' work in that respect.”

Echoes of Time book cover

Book Two

Echoes of Time

They became a separate species, a new evolutionary path.

Read the blurbClose

Splintered minds. A hidden city. Alien evolution directed by thought alone.

Seventy years have passed since Kera unlocked the secrets of the dummy node, and the Administration reigns supreme. But all is not as it seems. Half-minds satisfy the Administration's ruling class, and now the true leader wants to emerge from the shadows.

Meanwhile, on the desolate plains of Barrenscape, an attempt to trap the Breaker goes awry, unveiling an ancient structure from a time so distant that even the Vaesians have forgotten. The Breaker's lair may have been found, but it's not what anyone expected.

“Echoes of Time shows how the middle of a trilogy should be done. One of the best sci-fi series I've read in at least a decade.”

Echoes of Foundation book cover

Book Three

Echoes of Foundation

Long before the dawn of my civilisation, your kind existed.

Read the blurbClose

The Source has entered its final phase. Fadin is in ruins following an influx rebellion and Sunsprit teeters on the brink. The Breaker wreaks havoc and a shadow of the Administration's leadership works to annihilate everything, under new orders from the Source's terrifying creators.

Separated from their friends by a strange anomaly, Kera and Diyan find themselves in a realm inhabited by confounding creatures eager to learn what became of one of their own. Meanwhile, Paran and Yena are drawn beneath Ringscape's surface, where they uncover dark truths of the Vaesian past, and why it was purposely forgotten.

Can the mysteries within the Source be solved before it is too late?

“James Murdo has finished out this trilogy with another story so action packed that it kept me going every time I took it up. The world building and characters are great.”

The series · Ongoing

Wanderers series

A lone Wanderer ship has found something on an innocuous world, something inexplicably connected to the mysterious entity that started the war.

Gil's World book cover

Wanderers Book 1

Gil's World

A war that ravaged the galaxy for hundreds of millions of years.

Read the blurbClose

After a relentless war ravaged the galaxy for hundreds of millions of years, an insidious enemy was finally subdued by the events of the Great Conflation, although not defeated. With the pre-Conflation empires in ruins and the Ascended Biologicals wiped out, the decimated galactic community struggled to rebuild itself from the ashes, and the machine-led Wanderer civilisation rose to prominence.

A lone Wanderer craft-lect, a sentient machine intelligence, has found something on an innocuous world it had marked for routine decontamination. Something that may aid it in finally discovering answers about their formidable enemy, and with the power to stop it.

Gil, a young woman from an isolated commune, realises that her abilities far surpass anything she had suspected, but do they come at a price?

“This is not your typical space opera. This story is much bigger and much more personal.”

Searching the Void book cover

Wanderers Book 2

Searching the Void

Its absurd claims of other realities can't possibly be true, can they?

Read the blurbClose

Now a passenger on the Wanderer ship, Gil struggles to comprehend its galaxy-spanning quest and her place amongst the stars. She is helped by 998, the c-autom appointed by the craft-lect as her guardian, while it also deals with its own burgeoning duties as quasi-leader of its kind.

The ship's other recent passenger, One-oh, an ancient bio-lect and assumed sole survivor of an ancient race, has meanwhile retreated into self-imposed isolation, although dark secrets about a terrible past threaten to be unleashed.

Elsewhere, paradise is tirelessly tended to by its devoted workers, keen to aid their forgetful creator in remembering vital knowledge that was lost. A new arrival could jeopardise everything.

“The blend of biology, science, technology and engineering is staggering.”

Infinite Eyes book cover

Wanderers Book 3

Infinite Eyes

This time, it's not just angry. It's vengeful.

Read the blurbClose

When a powerful machine-lect reconnects with real space to gaze across the galaxy, it receives an unexpected message and decides to take action.

The Maspero, an Ascended Biological civilisation extinct for sixty million years, may hold vital clues about the fabled Deliverer. The craft-lect is nearby, but there's a problem. An internal attack has removed its control and left it isolated from the crew. Just where do One-oh's loyalties lie?

Tor and DeVoid try to make sense of their uninvited guest as well as his bizarre request, while Apalu faces a difficult choice on its quest to the Lenbit Orbital, and a terrible weapon lies in wait from the dawn of the Wanderer civilisation.

“What an amazingly unique tale. If you liked Gil's World, you will love this book as well.”

The Outer Layer is an enigma to its residents. Representatives from countless races and civilisations wander the many territories, hoping to unlock its secrets and progress further into its depths.

An anomaly has been detected in space by an artefact from an extinct civilisation. Ciqalo, a machine intelligence from the Wanderer civilisation, is tasked with leading the investigation in the hope of weaponising it for a galactic war.

Tolren, playmate of an heir to the Alexis-Meld, becomes a hunted fugitive and finds himself aboard a structure in space that defies all understanding, alongside Seremend, a fellow Roranian. They race to comprehend their new home, and why they have been chosen.

Fractured Carapace

How does an entire star system vanish?

Read the blurbClose

Chiton vanished. It was there, and then it wasn't. The Chitchi were forced to start again.

Three hundred years ago, the brilliant Krasna established her research c'hub on the unclaimed water-world of Prebis. Chiotechnology may have its flaws, but finally her ferinon experiments seem to be going somewhere. Unfortunately, her increasingly bizarre behaviour and strange references to the past begin to worry her subordinates.

Chathindi studies the insectoid Risers, non-sentients native to Prebis, and grows increasingly convinced they are more than they appear. Just who is observing who?

“A fun and unique story in the Wanderer Universe, with a glimpse into a distinctly alien, yet all-too human, civilisation.”

About the author

Cerebral sci-fi, with the emphasis on the sci.

I write space opera and hard science fiction blended with other sub-genres, all of it set in the Wanderer Universe. Reading hard sci-fi and space opera when I was younger led me to study physics at university in London, and the books are what happened next: big ideas, strange intelligences, and mysteries that take more than one novel to unfold.

If you enjoy Iain M. Banks, Alastair Reynolds, Neal Asher, John Scalzi, you will probably feel at home here. You can read more about the authors who shaped the universe.

A note for other writers: I keep a glossary for every book, and for years I used a little tool of my own to build them. That tool grew up and moved out. If you write fiction with invented names and terms, try the glossary generator I still use for every manuscript. It is an online glossary maker, nothing to install, and the first pass is free.
