Meanwhile, the last survivors of Earth, escaping a dying planet, travel aboard the starship Gilgamesh in search of a new home. Their only hope is the very planet where the now-intelligent spiders reign. As humanity’s desperation grows, a collision between the two civilizations seems inevitable. But will it lead to war or an unprecedented alliance?

A sweeping, multi-generational epic, Children of Time explores evolution, intelligence, and what it truly means to be human. With thought-provoking themes and a unique take on alien life, Adrian Tchaikovsky’s novel is a masterpiece of speculative fiction

3. Summary

Children of Time – Chapter-Wise Summary

Chapter 1: The Fall of the Ancients

Dr. Avrana Kern, a brilliant but arrogant scientist, oversees the launch of a groundbreaking experiment: a nanovirus designed to uplift primates on a newly terraformed planet. The goal is to accelerate their evolution into a sentient species capable of advanced thought. However, before she can release the monkeys, a sabotage attempt destroys the mission. The primates perish, but the virus survives, left alone on the planet to take its course.

As the sabotage unfolds, Kern narrowly escapes in a satellite station orbiting the planet, where her consciousness is later uploaded into an AI system. Trapped in a mechanical form, she watches over her failed experiment for thousands of years, unaware that the nanovirus has found a new host—spiders.

Chapter 2: The Exodus Fleet

Thousands of years after Earth's downfall, the last remnants of humanity flee a dying planet aboard the colony ship Gilgamesh. The crew, led by the pragmatic but ruthless Commander Guyen, seeks a new home for their species. Among them is Mason Holsten, a historian and classicist whose expertise in ancient human records becomes vital in deciphering pre-Collapse messages.

The desperation of the crew is evident—humanity’s survival depends on finding a habitable planet. However, resources are dwindling, and tensions among the crew begin to rise. As Holsten studies Kern’s old transmissions, it becomes clear that this planet might not be unoccupied.

Chapter 3-6: The Spiders Rise

With the monkeys gone, the nanovirus latches onto another species—Portia labiata, a type of jumping spider. Over generations, the virus enhances their cognitive abilities, fostering communication, social behavior, and strategic hunting.

Early spider societies begin to form, with key figures like Portia and Bianca, two evolved spiders who start understanding rudimentary cooperation. They learn to work in groups, hunt larger prey together, and even experiment with basic tool use. Unlike normal spiders, who are solitary, these creatures develop a sense of community.

Meanwhile, back on the Gilgamesh, the crew starts noticing strange anomalies in the transmissions from the planet. Kern’s AI, still functional, continues to broadcast warnings, instructing humanity to stay away.

Chapter 7-10: Human Struggles

As tensions aboard the Gilgamesh worsen, Commander Guyen becomes increasingly dictatorial, focusing on his vision of securing a home for humanity at any cost. Holsten and his fellow crew members—particularly engineer Lain—struggle to maintain order, knowing that landing on an occupied world could be disastrous.

On the planet, the spiders advance rapidly, developing primitive agriculture, social hierarchies, and even mathematics. Generations of spiders refine these skills, unknowingly outpacing human civilization in many ways.

When the Gilgamesh attempts a descent, they are met with unexpected resistance. Kern’s AI, which sees itself as a guardian of the planet, retaliates with orbital defenses, forcing the humans to retreat.

Chapter 11-15: The Spiders Advance

The spiders have now formed structured societies, with female spiders leading the colonies while males, though weaker, serve as crucial partners in research and development. Portia's descendants continue to push the boundaries of their intelligence, experimenting with written symbols, domestication of ants, and a unique computing system based on pheromones.

At the same time, Kern’s AI starts exhibiting signs of insanity—a fragmented mind trapped in orbit, caught between its original purpose and a growing god complex. She begins to view the spiders as her children, nurturing their growth but also enforcing strict barriers against human interference.

Back on the Gilgamesh, mutiny brews as Lain and Holsten realize that Guyen’s reckless leadership is driving them to extinction. A desperate gamble is made—entering cryosleep for hundreds of years in hopes of waiting out the situation on the planet.

Chapter 16-20: Kern’s AI and Human Conflict

Centuries pass. When Holsten and the remaining crew awaken, they find Guyen missing and the Gilgamesh barely functioning. The spiders, meanwhile, have reached an Industrial Revolution-like stage, discovering mechanical devices and advanced war strategies.

Kern’s AI, now fully detached from its original human self, prepares to wipe out the remaining humans, seeing them as inferior and destructive. However, some of the spiders begin to question their world’s history, theorizing that their rapid evolution wasn’t natural.

Holsten finally deciphers the full pre-Collapse messages, realizing that Kern had intended to uplift primates, not spiders. Humanity was never supposed to be the inferior species—but they now are.

Chapter 21-25: Spider Space Age

With the spiders reaching a space-age level of advancement, they begin constructing rockets and satellites, hoping to understand their “goddess” in the sky—Kern’s AI. At the same time, factions emerge:

• Traditionalists, who revere Kern and want to obey her commands.

• Revolutionaries, who question Kern’s control and seek their own destiny.

Meanwhile, the Gilgamesh’s systems begin to fail, forcing the humans to make a final desperate decision: engage with the spiders in diplomacy or risk extinction.

Holsten, now aged and weary, becomes the reluctant mediator between two vastly different civilizations—one biologically advanced, the other technologically stagnant.

Chapter 26-30: The Final Confrontation

In the book’s climactic moments, the spiders reach full sentience and self-awareness, realizing that Kern’s AI is not a deity but an old, broken human creation. A council of evolved spiders, led by Portia’s descendants, makes a radical decision: instead of wiping out humanity, they will help them.

The Gilgamesh’s crew, now dwindling and desperate, lands on the planet for a final negotiation. Instead of war, the spiders offer integration, allowing the last humans to become part of their society rather than perish.

The book ends on a hopeful but philosophically complex note—humanity, once the dominant species, is now the lesser race, at the mercy of creatures they would have once dismissed as insignificant.

4. Analysis

Analysis of Children of Time by Adrian Tchaikovsky

Characters

• Dr. Avrana Kern – A brilliant yet arrogant scientist who initiates the terraforming project to uplift monkeys into sentient beings. After a disaster, she becomes an isolated AI overseeing the experiment for centuries.

5. Review

REVIEW: Children of Time by Adrian Tchaikovsky

My Opinion

Children of Time is a brilliantly imaginative and ambitious sci-fi novel that explores themes of evolution, intelligence, and survival on a cosmic scale. Adrian Tchaikovsky masterfully weaves together two parallel narratives—one following the remnants of humanity searching for a new home, and the other chronicling the rise of an unexpected civilization of intelligent, uplifted spiders on a terraformed planet.

The novel begins with an experiment gone wrong. A scientist, Dr. Avrana Kern, intends to uplift monkeys on a distant world using a nanovirus, but due to unforeseen circumstances, the virus instead accelerates the evolution of spiders. Over generations, these spiders develop complex societies, languages, and even technology—creating a fascinating, non-human perspective on civilization. Meanwhile, a desperate group of human survivors, aboard a failing ark ship, stumbles upon this planet, leading to a high-stakes confrontation between two intelligent species.

Tchaikovsky’s world-building is breathtaking, and his ability to make readers empathize with non-human creatures is a rare achievement in science fiction. The novel is equal parts thought experiment and gripping survival story, with deep philosophical questions about intelligence, progress, and cooperation.

Why It Is Worth Reading

Children of Time is one of the most original sci-fi novels of recent years. Instead of the usual human-centric perspective, it forces readers to consider intelligence and civilization from an entirely alien viewpoint. The evolution of the spiders is both scientifically plausible and emotionally compelling, making their struggles and triumphs just as engaging as those of the human protagonists.

The novel also provides a fascinating reflection on humanity’s tendency toward destruction and short-term thinking, contrasted with the slow, calculated progress of the spiders. It challenges conventional ideas about what makes a species dominant and whether cooperation or competition leads to survival.

For Whom It Is Recommended

This book is perfect for fans of epic, idea-driven science fiction. If you enjoyed The Three-Body Problem by Liu Cixin, Blindsight by Peter Watts, or Rendezvous with Rama by Arthur C. Clarke, you’ll likely appreciate Children of Time.

It’s also a great read for those interested in evolutionary biology, artificial intelligence, and speculative futures beyond human dominance. However, if you prefer character-driven stories with heavy emotional arcs, you might find the book’s broad scope and intellectual focus a bit detached.

Criticisms

While Children of Time is an incredible feat of storytelling, it can feel slow at times, especially during the detailed evolutionary sequences of the spiders. Some readers may struggle with the scientific depth and the gradual, multi-generational storytelling approach.

Additionally, the human characters, though interesting, sometimes feel secondary to the grand ideas at play. The pacing, particularly in the middle, may test the patience of readers who prefer more action-driven narratives.

Despite these minor drawbacks, Children of Time is a must-read for serious sci-fi enthusiasts. It’s a rare novel that is both intellectually stimulating and emotionally satisfying, offering a unique perspective on the future of intelligence and survival in the universe.

6. About the Author

About the Author

Biography

Adrian Tchaikovsky is a British science fiction and fantasy writer best known for his innovative worldbuilding and exploration of evolutionary themes. Born in 1972 in Lincolnshire, England, he studied zoology and psychology before switching to law, later working as a legal executive while writing novels.

Tchaikovsky’s work often blends deep scientific concepts with compelling storytelling. His Children of Time (2015) won the Arthur C. Clarke Award and is widely regarded as one of the best modern sci-fi novels. His writing is characterized by its intricate plotting, intelligent non-human perspectives, and philosophical explorations of survival, intelligence, and civilization.

What Inspired the Author to Write the Book

Tchaikovsky was inspired by his fascination with evolutionary biology and the concept of uplift—where non-human species are artificially advanced to higher intelligence. He wanted to explore what would happen if a species other than humans developed sentience and formed their own civilization.

He was also influenced by classic sci-fi themes, particularly those found in works like The Legacy of Heorot (Niven, Pournelle, Barnes) and 2001: A Space Odyssey (Clarke), which examine human encounters with other intelligences. However, instead of aliens, Children of Time focuses on an intelligent species evolving naturally over generations—Portia labiata, a species of jumping spider.

His background in zoology played a major role in crafting the book’s evolutionary narrative, showing how intelligence and cooperation might develop in a non-mammalian species.

Influences from the Author’s Life in the Book

Tchaikovsky’s love of insects and his academic background in biology directly shaped Children of Time. He carefully constructs the spiders’ cognitive development, social structures, and language, ensuring scientific plausibility while maintaining a gripping narrative.

His interest in psychology is also evident in the novel. The contrast between human survivors—struggling with their declining civilization—and the spiders—progressing through scientific and cultural revolutions—mirrors real-world historical cycles of societal rise and collapse.

The novel also reflects Tchaikovsky’s philosophical interest in intelligence itself: What makes a species "superior"? Can different forms of intelligence coexist, or is conflict inevitable? These questions drive the tension between the human remnants and the spiders, offering a fresh perspective on interspecies relationships.

With Children of Time, Adrian Tchaikovsky delivers a masterpiece of evolutionary science fiction, blending biology, philosophy, and deep storytelling to challenge human-centric narratives of intelligence and survival.
