[02] · The story

Sixteen
silences.

On April 15, 2387, at 14:02 solar meridian time, the Sentinel-016 buoy falls silent. In the fifty-seven minutes that follow, fifteen more installations — beacons, relay stations, a flight academy where one woman learned to call herself a pilot — drop off the map.

No one has seen the enemy. No one knows what it looks like. The probes return only terminal vocalization, incomplete: half-words, clipped exclamations, a mother— that never finishes.

Inside the simulated cockpit of a Falcon fighter, on the training deck of the Hecate-7, Lieutenant Elena "Nova" Reyes watches the holomap. Fourteen. Fifteen. Sixteen. And she understands, with her gut rather than her head, what her father felt the day he learned he was going to die: the sensation that the universe had just taken one step to the side.

"Beacons are beacons. They exist so that the lost can find their way home. And someone had just put sixteen of them out."

One fleet.
One frontier.
A new kind of silence.

In 2387 humanity has colonized the solar system. Fleets guard the outer orbits with networks of buoys, beacons, and patrol stations. This is the technical and visual cartography of that world.

// SHIPS & INSTALLATIONS

// THE UNIVERSE IN MOTION

Recruitment posters, fleet brands, visual archives leaked from the Sentinel network. Material still circulating, year after year, across stations, orbital markets, and civilian radios of the system.

"Space doesn't make noise; it entered her from the inside, and she let it enter, and she understood then, for the first time in her life, the word silence with her gut instead of her head."

THE NOTE
THAT WAITS.

In the book, a four-note hum is passed from a dead pilot to her living wingmate. It isn't a decorative detail: it's one of the emotional axes of Book I.

Those four notes are real. Ecuadorian composer Julián Machuca Ramírez recorded them as a starting point, and is still building a full piece around them. You can already hear the seed of it.

LISTEN TO THE TRACK

"In my language, an interrupted song has its own name. kethana nivra. It means… the note that waits."

"
The expectation this fragment gave me is that of an interesting and entertaining thriller — a war of species fighting to govern a territory. Similar to what happened centuries ago with the discovery of America, and all the bloody fights to rule that land.

There's a paragraph in the prologue that made me close the book and not open it again until the next day. Not out of boredom. Out of respect.

The silence of the prologue has the same texture as the final chapter. That's structure. That's craft.

CARLOS DONOSO FIRST STORY · 2018

[09] · About the author

A story
that took seven years
to find its first paragraph.

My name is Carlos Donoso. I'm from Cuenca, Ecuador. My first short story was written in 2018: Julián Matadero, a story shaped around the Tomebamba River and inspired by the birth of my son Julián Matías in April 2016.

Between 2018 and 2020 I wrote stories of different sizes: some short, some deeper, some made simply to entertain. Part of that archive lived at cuentos-ecuador.com. During that period I also wrote a dreamlike story about my bus trips to Quito.

Later I wrote letters to people I loved, as well as technical articles and a developer-help blog that stayed online until April 2026. I began La Semilla de Hierro, published in English as A Memory of Iron, in 2025 and finished it in May 2026. It is a self-contained novel and Book I of the Iron and Void Saga.

"I'm not interested in epics that forget the last names. I'm interested in epics that archive them with microsecond precision and respect them, one by one."

WHAT PEOPLE
ASK.

Where can I buy A Memory of Iron?

A Memory of Iron has been out since July 5, 2026. Three ways to get it: Kindle on Amazon for $5.99, paperback on Amazon for $15.99 (ships worldwide), or a signed printed copy in Ecuador for $14.99, ordered over WhatsApp.

How much does it cost?

Kindle ebook: $5.99. Paperback on Amazon: $15.99. Signed printed copy inside Ecuador: $14.99. All prices in USD. Amazon adjusts the local equivalent in each store, so what you see at checkout may differ by a few cents.

How do I get a printed copy in Ecuador?

Write to me over WhatsApp and I'll sort it out with you directly. The copy costs $14.99, comes signed, and I either hand it to you in Cuenca or ship it anywhere in the country. No Amazon import fees, no customs wait.

What is A Memory of Iron about?

A Memory of Iron opens in the year 2387, when sixteen installations go silent in under an hour. Lieutenant Elena "Nova" Reyes, a Seventh Fleet pilot, discovers that the war she knew has just changed shape.

Who is Carlos Donoso?

Carlos Donoso is the author of A Memory of Iron and creator of the Iron and Void Saga. He writes literary military sci-fi focused on memory, grief, technology, and intimate epic. On Instagram @ironvoidsaga he posts exclusive material from the universe every day.

In what format is it published?

Digital (Kindle, $5.99) and paperback ($15.99) via Amazon KDP, plus signed printed copies inside Ecuador ($14.99). A hardcover edition is being evaluated for late 2026.

In what languages is it available?

In English as A Memory of Iron — the edition you're looking at — and in Spanish, the original, as La Semilla de Hierro at the Spanish site. Both editions are out now. Other languages depend on serious publishing offers.

How many books are in the Iron and Void Saga?

A Memory of Iron stands on its own — and it is also Book I of the Iron and Void Saga. Book II is in development. Each book is meant to be read as a whole inside the larger arc.

Is this hard sci-fi or literary sci-fi?

Both. The technical details (vectors, coordinates, telemetry) are carefully handled, but the heart of the book is literary. If you loved Dune by Herbert or The Three-Body Problem by Liu Cixin for their human layers, this will speak the same language.

What books is A Memory of Iron similar to?

If you enjoyed Becky Chambers' character-driven warmth, Arkady Martine's literary space opera A Memory Called Empire, Ann Leckie's Ancillary Justice, Ursula K. Le Guin's humanist speculative fiction, Joe Haldeman's The Forever War, or Emily St. John Mandel's literary prose in speculative settings, this book lives in the same neighborhood: military sci-fi where memory, grief, and silence carry more weight than the battles. One difference — it was written in Spanish by an Ecuadorian author and translated for English readers, so it brings a Latin American voice to the genre.

When does the canon short story arrive?

As soon as you subscribe, you're inside the archive. In the next few days you'll receive "Méndez's Ring" — 22 pages in PDF and EPUB. It's full canon, happens minutes before the book's prologue, on the Sentinel-016 buoy. Meanwhile, on Instagram @ironvoidsaga there's exclusive material every day.

Is there violent or sensitive content?

The book is about a war. There's death, grief, carefully written violence. No gratuitous gore, no sexual violence. Recommended for readers 16+.

Where can I see your previous work?

My personal blog with short stories and illustrations lives at carlos-donoso.com. This is my first full-length novel.

How do I unsubscribe from the newsletter?

Every email has a one-click unsubscribe link, no questions asked. You can also go to https://www.carlos-donoso.com/memory-of-iron/unsubscribe.php and paste it from your inbox.
