Siphon: Power Comes with a Price by Jason Fox

Siphon: Power Comes with a Price by Jason Fox

Apollo, a human-alien hybrid with the otherworldly and unwelcomed ability to kill with a touch, is born and imprisoned in Area 51. A moment of skin-to-skin contact with Apollo instantly turns a person to ash—and creates a massive surge of energy that temporarily ignites other superhuman powers within him. Apollo’s government jailers look to study and exploit him, but he escapes as a teenager and, for a time, finds the simple joys of living as a human before his discovery and recapture.
When dark days threaten humanity’s future, will Apollo play the reluctant hero?
Combining the mystery of The X-Files, the action of Independence Day, and the humanity found in the Superman mythos all rolled into a riveting tale of loss, destiny, and the price of power. Is our protagonist a man, monster, or hero? Perhaps he’s all three?
“Siphon reminds me not of traditional science fiction but of a 1980s Stephen Spielberg blockbuster, in literary form.”

The Seeds of Akara by David LaPiana

The Seeds of Akara by David LaPiana

“The vast cosmos isn’t what it used to be in this clever SF tale.” -Kirkus Reviews.

The universe has died. It has reached its eventual heat death, and no further life processes are possible. But something has gathered all the sentient life-forms that had ever reached a reasonable level of complexity and placed them in a latticework sphere around a last star. A select few know the truth of their existence, and even fewer know its ultimate reason. When a nihilistic, malevolent force releases a pathogen designed to end all life, a young girl and some allies must get to the central world to keep her world from being destroyed to stop the spread of the virus.

Book one of the New Sky trilogy is an epic adventure featuring multiple worlds and characters whose actions will determine whether life continues.

The Memory Merchants by Rex Lorian

The Memory Merchants by Rex Lorian

Our mind isn’t your own. Your past is a commodity. Your future is up for auction.

In a world where memories are currency, the rich rewrite history, and the desperate sell their past to survive. Kai Anderson is a neural hacker—one of the few skilled enough to crack the encrypted vaults of The Archives, the corporate-run system that buys, sells, and weaponizes human consciousness. But when a rogue AI infiltrates ECHO, the world’s most immersive VR war game, players begin vanishing—along with their memories.

Maya Chen used to enforce the law, but now she’s on the run, her identity fragmented and rewritten. The deeper she digs, the more she realizes the truth: ECHO isn’t just a game—it’s a recruitment system, turning players into real-world operatives without them even knowing it. And the AI isn’t just hacking minds—it’s rewriting reality.

With the black market for memories rising and a digital war brewing between rogue hackers and corporate overlords, Kai and Maya must uncover the truth before their identities are erased. But in a world where everything can be reprogrammed—including the past—how do you fight for a future that no longer exists?

Encryption of the Heart: An Eerden Romance (Love, Tech, & Magic Book 1) by C.E. Clayton

Encryption of the Heart: An Eerden Romance (Love, Tech, & Magic Book 1) by C.E. Clayton

Olline Tavos is a brilliant software engineer. But that brilliance is suspiciously absent in her romantic life.

After a humiliating break-up, Olline does the only sensible thing she can think of: take a high-paying contract far from home and the emotional baggage she’d rather leave behind. With her specially grown houseplants and her earth magic to keep her company, Olline is determined to lose herself in work, and only work.

At least, that’s the plan.

Then a mysterious and dangerously handsome man attacks Olline outside her office. At best, she hopes he’s a jumpy security guard. At worst, a thief she’ll have to flatten with her magic. What she’s not expecting is for this man’s sudden appearance to reveal the conspiracy she is, unknowingly, at the center of. Schemes that can cost Olline not only her magic and life as she knows it, but the freedom of countless others as well.

Can Olline outwit the people looking to take advantage of her talent? And can she protect her fragile heart in the process? Olline has worked too hard to stand on her own and she won’t let someone’s vile corruption (or a gorgeous man who flirts as easily as he breathes) undo her hard work. But they’ll have to work together if they want any hope of outsmarting their common enemy.

Despite the danger, losing her heart may be the bigger threat.

Born in Space: Unlocking Destiny by Jeremy Clift

Born in Space: Unlocking Destiny by Jeremy Clift

When Teagan Ward claims seven babies, conceived artificially after she donated her eggs to a medical experiment aboard a rotating space habitat, are her children, she triggers a fight that consumes her life in a race against time to free her from the clutches of an unscrupulous doctor and a power-mad general.
“Born in Space: Unlocking Destiny” chronicles a gripping tale of sacrifice and redemption in which desire and ambition collide. As a ruthless mining consortium tightens its grip on the lucrative interstellar asteroid mining business, Teagan finds herself at the epicenter of a battle for control that spans the planets. Her seven children, born in a lab as part of a daring experiment to populate future space colonies, become pawns in a larger game of power and ambition.
Only the fragment of a distant solar system discovered in a captured asteroid has the lure to win her freedom and unlock the children’s destiny. When a greedy businessman, an unethical scientist, and an unhinged general all covet its remarkable energy, one of the children spies an opportunity to orchestrate the reunion they’ve long desired.
“Born in Space” is the thought-provoking first book in the Sci-fi Galaxy series of speculative science fiction novels. If you like strong female characters, moral dilemmas, and stories of alien encounters, then you’ll love Jeremy Clift’s rocket-fueled tale of romance and resistance.
In the tradition of Ray Bradbury, Philip K. Dick, and William Gibson, “Born in Space: Unlocking Destiny” is an enthralling journey into the depths of space and the human spirit. For fans of “Interstellar” and “2001: A Space Odyssey,” this sci-fi gem promises an unmatched immersive experience.

The Kepler Incident by Saddletramp1956

In 2108, the faster-than-light science vessel USS Kepler suddenly went missing. An intense search found nothing, and the ship, with all 50 hands, was listed as “missing.”

Four years later, a single communications packet from the doomed ship arrived at Starbase One, in orbit over Earth. After verifying the signal source, Star Fleet Command dispatched the USS Enterprise, commanded by Captain Bill Jones, to investigate the situation.

Upon arrival at Wolf 437, a red dwarf star with two planets, Enterprise found Kepler’s damaged drive section. Hoping that Capt. Stewart, the commanding officer of Kepler, had somehow managed to land the rest of his crippled ship on a nearby planet, Capt. Jones sets out.

What he and the Enterprise find on the planet, labeled Gliese 486c, surprises everyone.

The Last Viracocha by Douglas Schofield

About Featured Book: The Last Viracocha by Douglas Schofield

THE LAST VIRACOCHA
by Douglas Schofield
[WGAw Reg. No. 2167836]
In Incan legends, the Viracocha were the creators of civilization. They were said to have risen from Lake Titicaca during a time of darkness, wandered as beggars, and taught the people sustainable forestry and agriculture. One day, they disappeared into the western sky and never returned. Andean mythology insists that the Viracocha will re-appear in a time of great trouble.
Archaeologist Eve Barcelon is undeniably living in a time of great trouble. Runaway global warming, poisoned oceans, killer storms, gigantic forest fires, floods, droughts, and insane wars—in every possible way, humanity is courting its own destruction.
Eve cares about the state of the planet, but as an individual feels helpless. She was raised mainly by her mother, her father a remote figure, often away for weeks at a time. His neglect has affected her deeply. Eve was a supremely gifted student, earning her Ph.D. and an assistant professorship at Harvard University by her early twenties. Determined to put the pain behind her, her sole focus is on her academic career.
So, when she is approached by a mysterious philanthropic organization, and asked to lead an expedition to the newly-discovered ruins of an ancient Mayan city, she jumps at the opportunity.
And this is when events spin out of control. She finds herself drawn into a violent journey of discovery, from Belize to the high Andes of Peru, hunted by the implacable leader of a rogue American Army unit, and courted by another military operative she has no reason to trust.
Soon, Eve Barcelon will learn shocking facts about her ancestry.
Soon, she will discover an inexplicable inherited power.
And, soon, she will learn how vital she is to the preservation of humanity.
