Jack Four (Polity Universe #21) by Neal Asher

This high-octane adventure is set in the same world as Neal Asher's acclaimed Polity universe. It's a thrilling, fast-paced standalone novel, perfect for fans of Alastair Reynolds and Stephen Baxter.

Created to die – determined to live . . .

Jack Four – one of twenty human clones – has been created to be sold. His purchasers are the alien prador and they only want him for their experimentation program. But there is something different about Jack. No clone should possess the knowledge that’s been loaded into his mind. And no normal citizen of humanity’s Polity worlds would have this information.

The prador’s king has been mutated by the Spatterjay virus into a creature even more monstrous than the prador themselves. And his children, the King’s Guard, have undergone similar changes. They were infected by the virus during the last humans-versus-prador war, now lapsed into an uneasy truce. But the prador are always looking for new weapons – and their experimentation program might give them the edge they seek.

Suzeal trades human slaves out of the Stratogaster Space Station, re-engineering them to serve the prador. She thinks the rewards are worth the risks, but all that is about to change. The Station was once a zoo, containing monsters from across known space. All the monsters now dwell on the planet below, but they aren’t as contained as they seem. And a vengeful clone may be the worst danger of all.

Neal Asher

Neal Asher is a name that rings out in the world of science fiction, particularly for those who crave gripping, high-concept stories filled with complex characters, advanced technology, and an exploration of the darker side of human nature. Asher’s writing has cemented his reputation as one of the most innovative voices in contemporary sci-fi, especially with his Polity series, a sweeping narrative that spans galaxies, alien races, and an ever-expanding vision of what humanity might become. His works are often a blend of hard science fiction, political intrigue, and the kind of action that makes readers’ hearts race.

Born in the UK, Neal’s childhood was marked by a fascination with science, technology, and the far-reaching potential of space exploration. His early interests in these subjects were only amplified by his love of speculative fiction, which led him to a career as a writer who could imagine both the wonders and dangers of a future shaped by technology. What makes Asher's writing stand out in the crowded realm of sci-fi is his ability to weave complex, often morally ambiguous characters into mind-bending futuristic landscapes. His books aren't just about the technology or the aliens; they’re about the people who interact with these elements—and the consequences of those interactions.

Asher’s Polity universe, a vast, interconnected series of novels and short stories, showcases his signature style: fast-paced action, intricate world-building, and philosophical undercurrents that touch on themes of artificial intelligence, corporate power, and the relentless pursuit of progress. The series spans multiple books, including Gridlinked, The Line of Polity, and The Cowl Chronicles, and has earned a dedicated following thanks to its dynamic characters and gripping plots.

But Asher’s world-building doesn't stop with the Polity series. His Transformation series is another example of his talent for creating immersive universes. Whether exploring the consequences of merging human consciousness with machines or pondering the future of space travel, Asher’s works are deeply thought-provoking, yet never forget to entertain. His stories aren't just about speculative ideas—they’re about how those ideas can shape our understanding of humanity, technology, and the universe itself.

Though he has received widespread acclaim for his contributions to the sci-fi genre, Asher remains an author who continues to evolve, challenging the boundaries of what science fiction can explore. His ability to infuse his narratives with thrilling plots, layered characters, and a deep sense of wonder about the future keeps readers coming back for more.

In his own words, “I write to make people think—and to entertain them while doing so,” a sentiment that perfectly encapsulates the essence of Neal Asher’s work. Through his books, Asher invites us to journey beyond our world, to see what could lie ahead—and to consider how far we might be willing to go to shape that future.
