Children of the Chronotron

In Short

When the ancient planetary life-support shield of Xlarn begins to fail, desperate immortals deploy a time machine called the Chronotron to alter history. An accidental temporal displacement snatches a contemporary passenger flight—including young Henry and the spirited English girl Martia—into a distant, primordial future ruled by eternal light and dangerous aquatic beasts. As ruthless survivors fracture into violent factions under figures like Tommy Weston, Henry and Martia uncover a vast galactic destiny tied to human origins, ultimately escaping a doomed world for the stars.

The Story

Facing planetary destruction as their artificial radioactive sky shield fails, the Xlarnan immortals invent the Chronotron to project an emissary across time. This multi-limbed alien, Mlargn, travels back to the twentieth century, inadvertently sweeping a contemporary military charter flight—carrying teenagers Henry and Martia, Uncle Andy, Valerie Roagland, and a mysterious armed passenger known as Scarface—into a strange, timeless era of perpetual daylight.

Stranded on a lush, tropical Earth billions of years in the future, the human survivors quickly fragment into uneasy camps. An aggressive and bitter passenger named Tommy Weston gathers armed malcontents, challenging authority and creating a harsh regime driven by deep-seated panic and desperation. Meanwhile, young Henry uses keen scientific deduction to figure out that the sun has dimmed, the thick ionosphere reflects trapped light, and they have traveled deep into the future. After witnessing horrifying local fauna like the swarming, flesh-eating devil lizards savagely devour a reckless crewman named Whitey, the castaways discover hidden subterranean structures, cairns, and advanced teletransporters left behind by ancient inhabitants.

Scarface reveals his true identity as Kimnar, a representative of a vast galactic civilization. He explains that Mlargn's historic child abductions—which originally sparked earthly legends like the Pied Piper—unwittingly seeded an alternate timeline of virile, space-faring humans who eventually overpowered the sterile Xlarnans. Now, the final remnants of Xlarn seek to destroy this alternate future, creating a multi-generational war across the continuum.

Back on Xlarn's deteriorating surface, as the dying planet faces inevitable annihilation from its failing reaction sphere, power struggles intensify. Tommy Weston and Dr. Edwards commandeer a rocket to escape the cataclysm, forcing Henry, Martia, and a loyal Indian Prince along as hostages. When the rocket launches into the searing, radioactive sky, the intense heat and explosions fuse its observation blisters, destroying Weston and Edwards. Amidst the blinding holocaust, a gleaming star-man sphere arrives from deep space. Kimnar, Henry, Martia, Kennedy, and the Indian Prince board the alien vessel, departing for a scintillating interstellar civilization. Simultaneously, back in the original timeline, a secret rocket experiment prepares to detonate a powerful D-C bomb on the moon, completing the vast cosmic loop.

How It Unfolds

The planetary crisis Facing imminent destruction as their artificial radioactive sky shield begins to fail, the Xlarnan immortals invent the Chronotron to alter history. Their multi-limbed emissary travels back in time, accidentally sweeping a contemporary military passenger flight into a strange temporal anomaly. This sudden disruption pulls everyday civilians, soldiers, and teenagers completely out of their familiar twentieth-century era.

Stranded in eternity The survivors find themselves stranded on a lush, tropical world governed by eternal daylight and populated by terrifying prehistoric wildlife. Swarms of flesh-eating devil lizards ruthlessly tear through human flesh in the water, driving home the brutal dangers of their new environment. Fear, isolation, and suspicion quickly cause the stranded passengers to fragment into hostile, warring factions led by ambitious men.

Unraveling the timeline Young Henry uses sharp scientific reasoning to deduce that they have traveled a billion years into the future beneath a cooled sun. He explains that a thickened, mirrored ionosphere traps light, creating the illusion of perpetual day without any visible sunrises. Soon, the castaways discover hidden subterranean ruins, mysterious cairns, and functional teletransporters left behind by ancient, advanced beings.

The galactic revelation The passenger known as Scarface reveals himself as Kimnar, a representative of a vast, space-faring human galactic civilization. He explains that ancient alien abductions originally seeded an alternate timeline of resilient humans who ultimately conquered the stars and challenged Xlarn. This stunning history entangles the survivors in an existential, multi-generational war spanning across the cosmic continuum.

Escape from the dying world Desperate rebels commandeer a rocket on Xlarn's surface to flee the collapsing reaction sphere, taking Henry and Martia as hostages. Searing thermal blasts destroy the rebellious leaders, but a gleaming star-man rescue sphere arrives from deep space. Kimnar, Henry, and Martia successfully board the alien vessel, escaping into an interstellar civilization while a secret terrestrial moon experiment concludes back on Earth.

The People

Henry is a bright, observant adopted orphan who wants to understand their bizarre temporal displacement and ensure everyone's survival. His obstacles include youthful skepticism from adults, hostile faction leaders, and lethal alien fauna, but he evolves into a crucial intellectual force who decodes the mechanics of time. Martia is a proud, pretty fifteen-year-old English evacuee who initially displays airs of snobbishness. Confronted with terrifying anomalies, she sheds her superficial prejudices, sharing a secret mental bond and deep resilience with Henry. Uncle Andy is a practical, level-headed construction engineer and Henry's guardian who strives to maintain order and protect his companions. Despite facing dangerous factions and unknown terrain, he remains a steady anchor of common sense. Tommy Weston is an aggressive, hot-tempered malcontent who wants absolute control over the camp. Blocked by government authority and his own volatile nature, his violent ambitions culminate in his fiery demise during the final rocket escape. Kimnar, initially disguised as the rugged "Scarface," is a sophisticated operative of the galactic civilization. He seeks to protect his advanced society from Xlarn's interference, ultimately guiding the surviving youths toward an interstellar future.

In Its Own Voice

Describing the desperate measures taken by the ancient alien civilization when their planetary environment began to collapse centuries ago, the opening historical exposition notes:

When their sun began to wane, the Xlarnans at first retreated underground to hoard the heat and life-supporting energies which their nuclear generators could supply.

Reflecting on the shocking appearance of the multi-limbed intruder inside the passenger aircraft cabin, the narrative details the creature's terrifying and complex physical features:

Under absurdly accentuated, hairless brows, a single, monstrous insect's eye with a thousand gleaming facets rotated about, examining them balefully.

Pondering their bewildering temporal displacement and the dangerous biological hazards of an unfamiliar world, Uncle Andy offers his fellow survivors reassuringly pragmatic guidance:

The most practical thing I can say is to relax.

What It's Really About

Beneath its fast-paced pulp adventure, the book explores the complex philosophical paradoxes of causality, time travel, and evolutionary destiny. It questions whether humanity's aggressive, resourcefulness-driven civilization can ethically supplant a sterile, dying creator race, framing existence as a vast, self-sustaining loop where cause and effect inextricably intertwine. The narrative closely probes human nature under extreme existential pressure, examining how civilized veneers quickly fracture when ordinary people are stripped of familiar societal structures and thrust into the unknown. Furthermore, it interrogates the heavy ethical weight of temporal intervention, asking whether altering history is justifiable to preserve a sprawling galactic future.

Why Read It Today

Classic science fiction enthusiasts who appreciate mid-century pulp imagination, complex temporal mechanics, and wild alien encounters will find plenty to savor here. Reading it feels like stepping into a breathless cinematic serial where historical folklore like the Pied Piper collides with far-future space opera and atomic-age anxieties. However, modern readers must navigate the book's period limitations, including mid-century social attitudes, rigid class stratification, and dated vernacular—such as the phonetic dialect used for characters like Pee Bee—that clearly reflect the cultural biases of its 1952 publication era. Despite these historical obstacles, the sheer narrative ambition, imaginative scope, and relentless pacing make it a fascinating artifact of speculative fiction's golden age. What stays with you long after finishing is the haunting concept of an infinite cosmic loop, where human history is simultaneously an accident of alien desperation and the seed of a vast galactic empire.
