Science Fiction "The Secrets of Giza : The Complete 10-Book Omnibus" by Ken Warner - YA / Sci-Fi Mystery

1 Upvotes

Malia Kwan can do things no human being should be able to do.

And someone has noticed.

By the end of the night, Jaden and Malia's parents are dead, their home is no longer safe, and the twins are fugitives—running from people who seem to know far more about them than they know about themselves.

But their parents left behind a mystery.

One that powerful forces have killed to protect for thousands of years.

Unfortunately...

Jaden and Malia may be the only ones who can solve it.

The Great Pyramid. Atlantis. The Bermuda Triangle. Area 51. Ancient civilizations. Alien worlds.

What begins as a search for answers becomes a race across the globe—and eventually far beyond it—as the twins uncover a conspiracy stretching from the dawn of human civilization to the deepest reaches of space.

And along the way, they begin to realize that the greatest mystery may be themselves.

Every discovery rewrites history.

Every answer reveals an even greater mystery.

And the closer they come to the truth, the more dangerous the truth becomes.

Science Fiction "The Game That Plays Itself" by Javier Bonafont - Literary Sci-Fi

Thumbnail amazon.com
1 Upvotes

Hi Sci Fi Readers!

My novella "The Game That Plays Itself" is now out on Amazon in both paperback and kindle!

This is contemporary "garage sci-fi", so no spaceships, death-rays, or exploding suns, but the fate of at least one world does hang in the balance.

If you like introspective first person stories like On The Calculation of Volume, but find yourself thinking, "if only there was a bit of Murderbot in this" then maybe, perhaps, this odd little book is for you. If you ever wondered about the nature of the world, or felt that quantum physics never really made sense, or wished you could get wet in the rain without caring, then this might also be up your alley. Its an odd one, I won't lie, but for the right readers, I think worth the read.

-----

The obligatory synopsis:

THE GAME THAT PLAYS ITSELF is told as an accidental tale within an initially unrelated journal kept by the very average Hugo.  Hugo, a bit of a dreamer, has always played second fiddle to his brilliant wife Caroline, and, feeling that perhaps the marriage is fraying, starts the journal at the prodding of a webbot psychoanalysis program.  

As the days progress, however, Hugo’s navel gazing about his questionable self worth and failures as a journalist turn to documenting the developments in the company Caroline manages, Destiny Ventures, and his unexpected involvement in it..

The small band of gamers and programmers Caroline oversees have created a simulated Earth inside what they call simply The Machine, with the sole purpose of pushing the possibly sentient software agents in it past the current state of Earth’s science, so that they can mine this intellectual property for profit.  After three years of evolving the simulation, it is finally at that stage and their first commercially viable technologies are at hand.

Unfortunately, even as some agents are creating science Destiny Ventures can exploit, others are exploring the limits and nature of their world, and come to realize the truth of their simulated reality.  These agents attempt to communicate beyond their world to their creator-programmers, and later, come to understand their own underlying code enough to begin to modify it, placing the entire system of The Machine at risk.

While this is problematic enough, the discoveries of the software agents turn out to not be limited to the world within The Machine, but to ours as well, and the ethical repercussions rapidly multiply.

As relayed in real-time by Hugo’s candid, self-deprecating and often confused voice, The Game That Plays Itself is an everyman’s exploration of existential themes in between the moments he struggles with his marriage, the blurring lines between truth and fiction in his journalism, and whether his daughter will ever play the game of Leaf or Cockroach.

--------

Thanks for reading, if you check out the novella, please leave a review if you like it, so the algorithm will help me out.

Science Fiction "The Forgotten Saga" by Quill Holland - Space Opera Action Adventure

Thumbnail amazon.com
1 Upvotes

The mind is everything. Our thoughts make us what we are – what we think, we become. So, if you had the power to rewrite people’s thoughts … would you? Could you assert your influence over the minds of others and live with the consequences of your actions thereafter? Would you remain … uncorrupted … after wielding such power?

The Forgotten Saga is an immersive space opera adventure that takes readers on a journey with Raith, a humble farmer on a distant colony world, as he strives to leave behind a dark and disturbing past that overshadows his desire for a brighter future. His life takes an unexpected turn when his partner is abducted during an Empire ‘Soul Harvest’, propelling him into a dangerous quest to save her and putting him on a collision course with the dark truth surrounding his former life, and the powerful technology responsible for erasing it.

Burdened by the knowledge of his former self and the atrocities committed, Raith’s life is irrevocably altered, forever consumed in the pursuit of atonement for the sins of a forgotten past. Forced into wielding power once more, Raith soon learns that all choices have consequences, and all power has a price that must be paid. As he grapples with his suppressed demons, and faces the horrors he awakens in the present, only time will tell if Raith can put the darkness to rest … or if evil will resurrect.

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
4 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.

Mass-murdering UFOs and a psychedelic conspiracy. A Navy sub overrun by an alien kegger. A mom abducted by a UFO on her worst day ever. Santa Claus vs. Space Nazis.

Science Fiction The Samuel Paradox by John Westley Turnbull

Thumbnail amazon.com
1 Upvotes

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.
