Throwback Thursday – Breathing Vapor

By Cynthia Sax on September 3, 2026

Breathing Vapor is a true enemies-to-lovers romance.

Vapor, the assassin cyborg hero, has Mira, the human heroine, as his next self-assigned target.

He believes Mira, his genetic match, is planning to harm him and his cyborg brethren.

Mira, however, has other plans for this sexy cyborg.

(grins)

Breathing Vapor

Vapor is the most advanced cyborg the Humanoid Alliance has ever developed. He’s a finely honed weapon, a warrior without parallel, half man and half machine. No lock can contain him. No being can stop him. Whatever he wants, he takes.

He wants Mira Breazeal, the Designer’s daughter.

She’s his one temptation, his sexy target. Vapor shouldn’t crave her caresses, steal her kisses, make her scream with ecstasy. The cyborgs want her dead and they would question his loyalty if he didn’t kill her. The humans would shoot him on sight if he dared to touch her.

Their love is forbidden. Their desire could be lethal. One human and one cyborg will risk everything for a moment of passion.

Throwback Thursday – Drift Would

By Cynthia Sax on August 6, 2026

Drift, a cyborg pilot, has a need for speed. (grins) He loves going fast.

So it is no surprise that when he locates his genetic match, while on a secret mission, he is all in.

Despite knowing or suspecting she can’t be trusted and she is definitely NOT who she says she is and she might, just might be trying to kill him.

***

Drift Would

A cyborg and a spy fly into danger.

***

Drift is one of the best pilots in existence, and he has been assigned a perilous mission.

The G Model cyborg must fly to a distant planet, locate the sector-destroying superweapon the enemy is projected to be developing there, and obliterate that threat to the universe.

When Drift arrives at his destination and meets with an informant, he’s distracted by a mysterious human female seated in the shadows. She’s Drift’s genetic match, and she is the one being he’s destined to care for, claim, and protect.

She’s also a liar and a thief. And she might be working with the enemy.

Trusting her could kill him and everyone he cares about.

Liar. Thief. Seductress. Saboteur. Roshini has been called all of those things. And she has earned each label. She’s done some terrible things to safeguard the beings she loves.

A gray-eyed cyborg warrior with nimble hands and a shared need for speed won’t stop her high-risk activities.

She’ll sacrifice everything, including her lifespan, to complete her self-appointed top-secret assignment.

***


Drift Would is a standalone, enemies-to-lovers, Cyborg SciFi Romance set in a dark, gritty, sometimes-violent universe.

It features a cyborg who loves to break speed records, a human spy with a talent for changing her appearance, and a foe intent on killing them both.

Throwback Thursday – Strike Zone

By Cynthia Sax on July 30, 2026

At the beginning of Strike Zone, there’s a masquerade (masqueradelike – it IS a futuristic story set on a different planet) scene.

I love the idea of masquerades. They’re parties. Everyone is masked. Beings can be whoever they want to be for the night. There’s mystery.

And there are a lot of opportunities for mistaken identity.

Which is exactly what happens in Strike Zone.

(grins)

Strike Zone

A cyborg devoted to duty…and to her.

***

While attending a party, Kesser, the daughter of her planet’s leader, witnesses the abduction of her best friend and her best friend’s mate.

She’s determined to rescue them. Preferably without fracturing the fragile peace agreement her mom has crafted with the abductors’ planet.

The only issue is…she has never participated in a retrieval mission.

Searching for assistance, she approaches the mate’s guard. The male, with his big broad shoulders and deep growly voice, affects her like no other being ever has.

Kesser wants him. She trusts him. And she requires his stealth combat skills.

Desperately.

Strike is no guard. The D Model cyborg has been sent to the sector to discreetly investigate a potential planet-destroying situation.

When a curvy human female with big brown eyes requests his help with a rescue, he doesn’t hesitate to say yes. She’s his genetic match, the one being he was manufactured to protect.

She’s also traveling to the next planet he has to search. He plans to claim his female while he fulfills his responsibilities to his kind.

Neither Strike nor Kesser realizes the dangers facing them are far greater than they imagine. Their enemies are converging, and one failed mission could doom the entire universe.

***

Strike Zone is a standalone, mistaken-identity, Cyborg SciFi Romance set in a dark, gritty, sometimes-violent universe.

It features a cyborg warrior with a finely honed sense of honor, a human support being taking on her first dangerous mission, and an evil that threatens everyone in existence.

Throwback Thursday – Intrepid Encounter

By Cynthia Sax on July 23, 2026

As a kid, I gobbled up stories about the Valkyries. These female warriors were awesome. They were mythical. They were fearless. They were battle maidens.

Intrepid, the cyborg captain of the Dauntless, is about to meet one.

And his world will never be the same.

Intrepid Encounter

Cyborg vs. Valkyrie

Blood will be spilled and hearts will be captured.

Intrepid and his crew on the Dauntless guard the border to the cyborg sector. The D Model cyborg captain has dedicated his lifespan to protecting their homeland. He’ll do anything to secure the space and keep his brethren safe.

That includes confronting a Valkyrie intent on vengeance.

The female warrior is beautiful, brave, strong…and Intrepid’s genetic match. She’s the one being he is fated to claim. Her voice causes his circuits to hum. Her touch produces a passion he struggles to control.

But if he has to stop her…permanently…to protect his kind, he will make that sacrifice.

Olrun has been tracking the whereabouts of a one-of-a-kind object. The stolen item is critical to the safety of her Valkyrie sisters, and she’ll do anything to retrieve it.

That includes waging war on a tall, broad-shouldered cyborg warrior sporting brilliant-blue eyes and grimly set lips.

The male might…just might…have battle skills matching her own. And that excites the immortal fighter. She craves his rough handling, his punishing embrace, his stern words.

But Olrun’s desire for the cyborg won’t distract her from achieving her goal. She will shield her fellow Valkyries from danger, even if that means ending Intrepid’s lifespan in the process.


Intrepid Encounter is an enemies-to-lovers Cyborg SciFi Romance set in a dark, gritty, sometimes-violent universe.
It features a protective cyborg, a vengeful Valkyrie, and a destiny neither of them can predict.

Throwback Thursday – Strive For Forever

By Cynthia Sax on July 16, 2026

Scientists discover something new about the planet we’re living on every dang day.

EVERY day.

So I know with 100% certainty there are forces in the universe we haven’t yet encountered.

Strive, the cyborg hero of Strive For Forever, is about to meet one.

(grins)

Strive For Forever


This cyborg seeks to vanquish an ancient entity and save his curvy human female.

Euryale made a terrible mistake. She opened a container she shouldn’t have touched and released one of the oldest lifeforms in existence. That all-powerful entity is now utilizing her as its host body and is slowly draining her energy.

Soon, she’ll die.

Euryale has accepted this fate and is determined to use her remaining moments in the universe to save as many lives as she can.

Her plans do NOT include a smoldering-hot, poetry-wielding cyborg willing to decimate entire planets to save her.

While under the control of the Humanoid Alliance, Strive, a K Model cyborg, disobeyed direct orders and refused to kill on their behalf. If he hadn’t escaped their cruel clutches, his defiance would have led to his death.

The male knowingly risked that fate to save the lifespans of complete strangers.

There is nothing he wouldn’t do to protect Euryale. The curvy human female is his genetic match, the one being he is destined to defend.

And she is in danger.

Strive would break every vow, cross every boundary, risk absolutely everything to keep her from harm.

Including battle a deity no one has ever defeated.

Strive For Forever is Cyborg SciFi Romance set in a dark, gritty, sometimes-violent universe.

Throwback Thursday – Testing Truth

By Cynthia Sax on May 14, 2026

I think of Testing Truth as my fairytale cyborg romance.

The human heroine is a princess. The cyborg hero is her dedicated (though rarely serious) warrior champion.

There’s a quest. And adventure. Love and, of course, the romantic happy ending.

(smiles)

Testing Truth

A fun-loving cyborg gets serious about love.

***

Truth lives each moment as though it were his last. The cyborg warrior rushes into danger, teases beings he shouldn’t provoke, accepts every call of adventure he encounters.

When a prissy little human princess floats into the Rebel structure Truth is occupying, seeking a mercenary to assist her and her unusual entourage, he volunteers to be her warrior. She claims their assignment is dangerous, warns him he might not survive the task.

That is exactly the type of fun he has been seeking.

Princess Nanette of the planet Royaume must rescue her estranged brother from an enemy prison ship. That is her duty, and she has been trained to always place the needs of her planet and her subjects before her own. Nancy doesn’t have the freedom to indulge her passions for a certain dark-haired, gray-skinned cyborg. Not permanently and not publicly.

But she is unable to resist the warrior. Truth, with his laughing eyes, smiling lips, and rough hands, tempts her as no one else ever has. He could be her one fleeting act of rebellion before she’s matched with the powerful ruler her planet requires.

If they survive their current mission.

Their love is doomed. Their lifespans are at risk. This cyborg and his princess will need the help of every ally they have if they wish to see another sunrise.

Throwback Thursday – North Bound

By Cynthia Sax on May 7, 2026

Steve, the sentient plant ruler of an entire planet, is one of my favorite minor characters I’ve ever written. Though he is not AT ALL minor. He is dominant to his very roots. Nothing happens on his planet without his approval.

And this includes any off world visitors. Like a cyborg second in command seeking to explore Steve’s planet.

Thankfully, North has a local warrior female to help protect him and his team.

IF she wants to do that.

(grins)

North Bound

A mission-focused cyborg battles a captivating and dramatic distraction.

***

North, the second-in-command of a cyborg crew, has two priorities—he has to explore and collect data on Balazoid Minor, a small planet in their sector, and he must bring his three-being team back to the ship alive and fully functional.

When he encounters his brash, bravado-wielding female, the one being genetically designed for him, he recognizes her for what she is—a distraction that might get him and his brethren killed. He WILL claim her, but only on his terms, when his mission is complete and everyone he is responsible for protecting is safe.

Myrina the Magnificent is the best warrior on her planet and possibly the universe. She has captured an unparalleled fourteen males for her all-female tribe. Once she has secured the fifteenth male, she will be a legend. Her name will live forever. She’ll earn the undying adoration of her sisters. Glory will be hers.

The male in her sights—and in her snare—is a huge, gray-skinned, blue-eyed cyborg with a skill for war and lips designed for kissing. One emotionally charged battle is all it takes for Myrina to realize she wants North for herself. She won’t share his caresses with anyone.

Their forbidden love might be destined to be, but it won’t be easy to maintain. Myrina will have to fight her sisters, an all-powerful male-eating plant, and her cyborg’s unbending will to make North hers and hers alone.

Throwback Thursday – Dominance And Dissent

By Cynthia Sax on April 30, 2026

Dissent is a champion of captured, tormented creatures everywhere.

Because the J Model cyborg was once a captured, tormented creature.

When he meets Greer, he feels her fear and her pain. He admires her will to survive.

And he knows…

the best way to care for the human female he loves is to eventually let her go.

Dominance And Dissent

To earn the love of his curvy human, this cyborg will have to set her free.
***
Dissent has one primary mission—to find his female and protect her.

He doesn’t know who she is, where she’s situated, or what she looks like. That doesn’t stop him from searching the universe for her. He’s a cyborg and he’s determined. He WILL track her down.

While the J Model warrior is exploring a settlement on a merchant planet, he hears a defiant scream. Dissent has finally located the one being he’s genetically compatible with. He rushes to his little human’s side, ready and willing to defend her, eager to claim his female…forever.

Greer has only one dream—to be free. She’s been a slave her entire lifespan, has been subjected to soul-crushing abuse and pride-shredding humiliation. When an opportunity to escape presents itself, she takes it. Steps away from independence, she’s apprehended.

As she looks death in the face, waiting for the final strike, a tall, handsome cyborg warrior saves her. He exudes power, makes her tremble with desire, is unlike any of the males she’s ever known…except in one heartbreaking way.

He wants to own her.

As Dissent and Greer battle for dominance, danger looms. An enemy from the past has returned. He’s heavily armed, he’s not alone, and his sole goal is to kill both of them.
***
Dominance And Dissent is a STANDALONE Cyborg SciFi Romance set in a dark, gritty, sometimes-violent universe.
It features an overprotective cyborg, a defiant slave, and a ravenous baby creature who is determined to eat his way through an entire settlement.

Throwback Thursday – Doc’s Orders

By Cynthia Sax on April 23, 2026

Doc’s Orders deals with a pandemic on an alien planet caused by visitors to that planet.

It was written long before COVID happened.

I felt this key aspect of space travel, heck, of ANY travel had to be addressed. Visitors spread illness. And sometimes those illnesses are unique to the local population. That can cause a pandemic.

Thankfully, the locals on the alien planet in Doc’s Orders have Doc, a skilled cyborg medic, and Allinen, a local with an interest in healing, to help them deal with their pandemic.

Doc’s Orders

She wants both sides of her cyborg—the medic AND the beast.


A fully functional cyborg is balanced. His machine half and his organic half work together to produce the perfect warrior.

Doc isn’t fully functional.

The G Model operates at the two extremes. When his machine is in complete control, he’s the logic-driven medic, saving lifespans. Once his organics take charge, he becomes the savage beast…and beings die.

Both sides of Doc want to be the first to claim his female.

Allinen is one of the few beings in her small settlement who wasn’t born with a fated mate. Determined to belong somewhere, she has crafted a plan to leave the planet.

That plan doesn’t involve a huge stormy-eyed male who alternates between cool seduction and out-of-control ravishment. Doc isn’t her fated mate. Allinen knows that. But his dual nature and forbidden embraces tempt her to forget forever and indulge in more immediate delights.

Neither side of Doc views their relationship as being temporary. Her conflicted cyborg is prepared to battle her family, her planet and death itself to keep her.

Throwback Thursday – Choosing Chuckles

By Cynthia Sax on April 16, 2026

Chuckles is a VERY grumpy wounded warrior. He is constantly in pain. And he is disillusioned with the world. One might say he has a beastly personality.

Bettina, aka Bait, has caused the disillusionment of many beings (most of them evil). (grins) She lies and she tricks beings…all for a good reason.

She is also Chuckles’ destined female.

Choosing Chuckles

A Cynical Cyborg Meets A Bad, Bad Female.

Chuckles hates all humans. In the past, humans betrayed him. That treachery caused permanent damage to his muscular form, resulting in a lifespan of pain. 

When the primitive D Model cyborg answers a distress call sent by a pink-and-blue haired, sparkly human female, he knows it’s a trap. He still has to respond to her fake cry for help. She belongs to him, is the one being genetically fabricated for him. But he plans to be her captor, not her captive.

Bettina, aka Bait, works with a team of females, snaring sexual predators in space, seizing their ships and transporting them to primitive planets. As soon as she speaks with Chuckles, she knows he’s not like the others. He has honor, is a being worthy of respect, of caring. 

But she can’t let him go. She has to trap him. His dominance thrills her. His deep voice evokes desires she’d never experienced in the past. She’ll risk it all, breaking every rule for one wild encounter with the male she calls Sir.
