THE MOONBASE 20 SERIES
On Moonbase 20, nothing is ever just a machine.
Beneath the humming lights and steady routines of a lunar colony, something else is listening. It taps through vents, whispers in fans, and hides in the quiet between heartbeats. Most people call it a glitch. The kids know better.
Follow Miri, Tala, and Jax as they solve mysteries no one else can hear—using patterns, patience, and the courage to ask questions adults are too busy to notice. Each book uncovers a new layer of the dome’s secrets, where science meets wonder and every clue matters.
From strange signals and shifting routes to ghost messages and breathing walls, the Moonbase 20 series blends mystery, science, and friendship into fast-paced adventures for readers ages 8–10.
These are stories about:
-
listening carefully when others don’t
-
solving problems with teamwork and curiosity
-
finding kindness inside complex systems
-
and discovering that even the quietest voices can change everything
Perfect for fans of The Wild Robot, City of Ember, and smart, imaginative science fiction, Moonbase 20 invites readers to lean in, count the rhythm, and listen back.
Because on this moonbase… the silence is never empty.
MOONBASE 20 Book One: A Space Colony, A Hidden Threat, and A Race Against Time
A Lunar Science Fiction Mystery of Sabotage, Secrets, and Survival
The first rule on Moon Base 20: Don’t ask about Echo.
For ten adults and their families, life on the Moon is supposed to be routine—oxygen checks, water reclamation, and hydroponic harvests in the Agricultural Dome. But survival on a lunar colony is fragile, and one mistake can be fatal. When the first Earth transport in years docks at Moon Base 20, the delicate balance shatters.
Mysterious lights appear far beyond the base perimeter. A critical drilling operation is sabotaged. Rumors spread about “the anomaly” hidden under the West Ridge, but the official reports insist nothing is wrong.
As tensions rise between the Operations crew and the secretive scientists at Research Station Echo, a group of kids begins to piece together a puzzle no one else sees—hidden storage rooms, stolen lunar samples, and encrypted transmissions from an Earthside contact named Jen Wei.
What they uncover could change humanity’s place in the solar system: an ancient structure buried deep beneath the lunar surface, older than the first Apollo landing—and possibly not of human origin.
But the closer they get to the truth, the more dangerous the game becomes. Someone will do anything to keep Echo’s secrets hidden. And in the final moments, one chilling discovery changes everything: the Moon holds two doors—and one of them is about to open.
If you love hard science fiction with mystery, conspiracy, and a trail of hidden clues to solve, Moonbase 20: Book One delivers a tense, slow-burn lunar thriller perfect for fans of The Expanse, Artemis, and Skyward.
MOONBASE Book Two: Descent’s Edge
The Moon was supposed to be silent. It isn’t anymore.
Life at Moonbase 20 was never easy, but after the first discovery beneath the ridge, nothing feels safe. The artifact pulses brighter. Dust flows uphill. And the ground itself seems to remember.
When a hidden fissure opens at the ridge’s edge, three friends—Jax, Anna, and Riley—find themselves pulled deeper into the mystery. Lieutenant Ruiz warns them: “It’s waking up.” But Ops and Echo can’t agree whether to study it, seal it, or pretend nothing is happening.
Secret logs, strange signals, and whispers of something ancient all point to one truth: the Moon has been holding its secrets for far longer than humanity has walked upon it. And now those secrets are stirring.
Book Two of the Moonbase series continues the thrilling adventure of science, mystery, and survival—perfect for fans of Percy Jackson and Animorphs, but set on the unforgiving lunar frontier.
MOONBASE 20 Book Three: The Chamber Opens
The dome survived the tremors. The Seals did not.
When the Vault Line splits open beneath the lunar ridge, Moonbase 20 becomes a refuge on the edge of collapse. Lights flicker. Oxygen scrubbers fail. Whispers ride the comms. And then Ruiz returns—claiming she never left orbit.
The adults build a story of control. Systems stabilized. Crisis contained. But the children know better. They’ve seen the light. They’ve heard the rhythm. The Core is no longer sealed.
As fractures spread through steel and trust alike, one truth grows impossible to ignore:
The Seals were never meant to keep humanity out.
They were meant to keep something else in.
Moonbase 20: Book Three is the next chilling installment in Jen Wei’s lunar thriller series, where survival is fragile, memory is dangerous, and some doors are never meant to open.
Moonbase 20 - Book Four: Listen Back
Miri, Tala, and Jax have discovered the Artifact beneath Moonbase 20 isn’t broken—it’s alive.
Its pulse has become a language: lamps blinking words, fans whispering rules, black intervals carrying messages too important to miss.
The adults call it “interference.” They want control. But when their attempt to synchronize the base goes wrong, only the kids remember Ruiz’s missing notes:
-
Do not shout.
-
Do not stretch the pause.
-
Doors are ears.
-
It answers when we listen back.
Armed with chalk marks, a recorder, and borrowed seconds, the children must mis-sync the base—creating a counter-beat to keep the dome’s ears open. Outside coordinates call to them, hinting at truths beyond the glass. Will they follow, or let silence fall forever?
Full of mystery, science, and friendship, Moonbase 20: Book Four – Listen Back continues the award-winning middle grade sci-fi series where listening kindly can save a whole world.
Perfect for readers who loved The Wild Robot, City of Ember, or A Wrinkle in Time.
