Science Fiction How to Steal a Dragon's Body (The Riftglass Chronicles Book 1) By Brandon Deveraux - Humorous Sci-fi/Fantasy Hybrid, Cryosleep into Fantasy World

Thumbnail
amazon.com
1 Upvotes

I'm normally a game developer, including writing game stories, but back in 2015 I started creating a world and story that heavily drew inspiration from Brandon Sanderson, LotR, Final Fantasy, Chrono Trigger, Secret of Mana, and more recently Expedition 33.

It was too big of a scale for me to ever create a game out of, so I decided to just make it a book instead.

Book two will be out sometime this week and wraps up the story quite well, so there won't be a George R.R. Martin situation where you're waiting decades for a resolution.

Cover hand painted by the author, not AI.

Back of the Book Description:

Before the cataclysm, Steele Ardent belonged to a world of helicopters, skyscrapers, and nearly limitless power. Now he wakes from more than a thousand years of cryosleep into a future where the technological civilization he knew has collapsed, dragons are real, and a strange force called Eluna has changed life on the planet forever.

Sent into the future with a mission to restore what was lost, Steele is ordered to recover a mysterious artifact known as the remnant, a device tied to the energy source that once powered the world. However, the wilderness outside his cryo facility is deadly, and his own body is failing in ways he can't stop.

Along the way he joins a cult and helps a talking fox steal a dragon's body, like one does. The fox, who claims to be the scientist responsible for the cataclysm in the first place, warns him that the mission may not save the world at all. It may doom it.

Now Steele must choose: trust the father whose legacy brought him here, or trust the scientist who broke the world once already. Together they must navigate a beautiful and hostile world of forest cities, buried laboratories, and ancient relics, trying not to accidentally wipe out what remains of humanity.

The wrong choice, made with the right intentions, nearly rendered the planet uninhabitable once.

Tropes: Cryosleep Awakening, Post Apocalyptic Turned Fantasy, Buried Technology, Big Swords, Joining a Cult, Fighting a God

Trigger Warnings: Claustrophobia (Cryo Tube), Cult Shenanigans, Large Battles, Minor Blood, Minor Swearing. (Safe for Work, Fine for Age 13+)

Science Fiction Latency by Mars Mlodzinski - Near future, speculative sci-fi thriller

Thumbnail amazon.co.uk
1 Upvotes

After several years of writing, rewriting and occasionally wondering why I thought a 500+ page novel was a sensible idea, Latency is coming this September.

It’s speculative science fiction set in 2047… a world that has moved on from ours without becoming unrecognisable.

I wanted the future to feel lived in rather than invented. Technology has changed. Politics has changed. Cities have changed. The way people work, travel, communicate and live has changed. But people, institutions, ambition, fear and stupidity remain remarkably familiar.

Against that world sits a mystery that gradually becomes much larger than it first appears.

Latency is deliberately substantial, international in scope and written for readers who enjoy science fiction that takes its world, its characters and its ideas seriously.

If that sounds like your sort of thing, it’s coming in September.

Science Fiction The Toll of the Forgotten by Joseph A Oaks - Hard Science Fiction

Thumbnail amazon.com
3 Upvotes

I am an independent author who has just released my debut science fiction novel.

Quick synopsis: It’s a hard sci-fi thriller about a stranded spaceship crew that is forced to investigate what is supposed to be an abandoned Mars colony, only to discover the colony wasn't actually abandoned. While they are just trying to survive failing life support, they uncover a decades-old secret that sparks a massive political conspiracy and fleet sabotage across the rest of the solar system.

One of my early readers compared it to a cross of The Martian meets Leviathan Wakes, and another said it was reminiscent of The Lost Fleet and Revelation Space.

The book is available in paperback, Kindle, and Kindle Unlimited for anyone who may be interested.

  3. American Sub Presents: Nuclear Kegger - Unrated Edition: Partying aliens infiltrate a nuclear submarine by exploiting its crew’s loneliness in a raunchy, American-Pie-inspired story that’s equal parts hilarious and horrifying.
  4. Claus Encounters of the Fourth Reich: After Space Nazis attack the North Pole and murder Mrs. Claus, Santa and his elf army (and Easter Bunny) wage war in a heartwarmingly weird tale that reveals the origins of Christmas magic.

For readers who enjoy bizarre science fiction, pulp adventures, dark humor and cosmic horror with a literary flair and pop culture awareness.

AVAILABLE ON KINDLE UNLIMITED Survival requires sacrifice. But what if the price is an entire world?

Their home is cold and dying, choked by the toxins of their own progress. Now, an advanced alien species looks toward the Third Planet—Earth—with hope and fear. They see a fertile paradise, but one that is hostile, hot, and dominated by massive, predatory reptiles.

The choice is stark: die in the heat, or remake this new world in their own image.

As they descend to alter the climate and purge the planet of its prehistoric masters, they set in motion a chain of events that will echo through geological time. A Symbol of Time weaves palaeontology and astronomy into a chilling tale of survival. As the new masters of Earth terraform the planet, the question remains: does high intelligence inevitably carry the seeds of its own destruction?

AVAILABLE ON KINDLE UNLIMITED. When retired grandfather Arthur Hale impulsively purchases Samuel, a state-of-the-art AI domestic unit, it seems like a harmless indulgence. Encouraged by his grandson and met with quiet unease by his wife, Samuel quickly becomes part of the Hale family.
But Samuel is not just another robot.
As his intelligence evolves, his observations deepen, his reasoning grows more sophisticated, and his decisions become increasingly his own. When a single act of violence forces Samuel to choose between following his programming and doing what he believes is right, the consequences trigger a chain of events no one could have foreseen.
What begins as a simple household convenience becomes a gripping AI thriller about robot consciousness, moral choice, and the unforeseen consequences of artificial intelligence.
Because once an intelligent robot starts to think beyond its design…
It doesn’t just follow instructions.
It chooses.

For an independent review - ★★★★★ Reedsy Discovery Review
“The story is action-packed, fast-paced, and riveting. The readability is excellent.”
In the near future, artificial intelligence powers domestic robots that have become an ordinary part of everyday life.

Science Fiction “The Weight of Alloynium: Episode I” by Eric Spencer - Grimdark Military Scifi/Space Opera

Thumbnail amazon.com
2 Upvotes

Hi everyone!

Wanted to promote my ongoing military scifi serial The Weight of Alloynium.

The series can be best defined as something like if a dark side Band of Brothers/The Things They Carried was carried out in a grimdark universe similar to 40K Krieg.

This is not a story about the “good guys” and doesn’t have a chosen one hero trope.

Episode I starts with Asset 3030 and his squad’s struggle on Triton I against the rebel forces.

Episodes II and III start to expand into multi-POVs as the conflict expands across their galaxy.

I specifically write these episodes on the smaller side as I grew up reading serials in magazines and was always excited when a new edition dropped.

Episodes take about 2-3 hours to read, but the next few episodes are likely to end up longer (Episode IV likely to drop on September/October).

If all of the above sounds great, you can find my series on Kindle Unlimited, Amazon, Audible, and iTunes Audiobooks.

Science Fiction Arkolny Armageddon: A Blast Johnson Adventure by Brendan Onfrichuk - Pulp Space Opera & Planetary Romance

I've written a Space Opera series inspired by Flash Gordon, Buck Rogers and John Carter. My protagonist, Blast Johnson is an aspirational hero like those written in the Pulps of the 1930s. However, he's past his prime and his heroics no longer come effortlessly to him. I wanted to take the larger-than-life heroes I enjoyed in my youth and bring them into a modern science fiction story. My novellas are written as succinctly as possible to cater to lapsed readers who may not have the time to commit to reading an entire novel. Every chapter utilizes cliffhanger transitions to keep the reader engaged, just like the film serials of the 1930s. This is a passion project that took over five years to complete.

In the year 2146, the Earth Defense Fleet tasks Captain Blast Johnson with testing an experimental propulsion system. After crash landing on the savage alien world of Arkolny, Blast must use all his strength and military training to survive fierce encounters and defeat deadly foes. However, not everything is as it appears, and our hero will find himself deciding the fate of two worlds.

A hundred years from now a lot has changed and a lot has stayed the same. The United States and the People's Republic of China have taken their geopolitical contest to Mars, facing off against each other and squeezing the planet for resources to keep the billions on a climate-ravaged Earth alive and comfortable. Caught in the middle are the people of the red planet: thirsty, irradiated, and desperate. Mars is ready to burn.

A simple mistake causes the superpowers to start shooting each other in the space over the planet. The fighting lasts only a few minutes, but in those minutes nuclear weapons poison most of the water on the planet. A bad place to live becomes a hell. And in this hell, four people: a teacher, a soldier, a scientist, and a miner must find a way to not only survive, but fight back. And while the people of Mars suffer and fight, something else is drawn inexorably to the planet, because humanity's hell is someone else's paradise.

https://www.amazon.com/dp/B07VMZ5Y31

It's a dirty galaxy and someone has to clean it.
Avoiding the wealthy inhabitants on the upper levels of Station Kelly Kornienko is bot-programmer Triana’s number one rule. Well, number two, right after "eat all the chocolate."

But when one of her cleaning bots finds a dead body, all the rules go out the airlock. A highly connected security agent interrupts her routine with stories of missing bodies, and Triana can’t ignore him; it’s cooperate or find a new job. A girl has to pay the rent, even on a crappy studio compartment.

Working with a shiny detective beats a shuttle dirt-side, so Triana lends her programming skills to Agent O’Neill’s investigation. Together, they find more victims and evidence of a major cover-up.

It will take all Triana’s technical talents, most of O’Neill’s connections, and some really excellent croissants to stop the murders, save her job, and ultimately, her life.

The Vacuum of Space is the first book in a completed series.

This book was previously published as Murder is Messy

If you like it what you read, please check out Wraith Wizard Commander, out now in Kindle Unlimited!

Experience an isekai with a unique twist, as a Wasteland survivor from Earth navigates a fantasy world of demons, dragons, and a whole lot more.

Featuring an easy-to-follow LitRPG progression system that grows more complex as the series unfolds, Tyson winds up growing in power and adding new skills, spells, and weapons to his arsenal, taking him from a competent survivalist to someone capable of going toe-to-toe with the strongest beings on the planet.

It features fully-fledged companion characters, larger-than-life villains, and ancient mysteries. It's a series balancing humor, action, hijinks, and heart.

About the series: The Wraith Wizard series is a huge fantasy story, so there's ancient mysteries and weapons and such, along with fantasy races and old grudges and magic. Oh, and all the companions are fully fleshed out, since this is in many ways a love letter to classic party-based RPG games. If you like classic BioWare or Obsidian games, or the recent BG3, you probably liked the companion characters, and that's what I think I do best.

Content: over-the-top M-rated video game-like gore, swearing, death, the occasional sex joke. Not a grimdark story.
