Description:

"An outstanding SF series debut that explores what it means to be human." – Kirkus Reviews (starred review)

No one has met a natural human before. No one has imagined the consequences.

Abducted from Earth and thrust into a bewildering alien world, Kali has no idea that she’s the only Earth-born 'natural' in a population of human pets and slaves scattered across the stars. Intelligent and persistent, she'll resist the limits of her captivity, turn her owner’s life upside down, and challenge everything he believes about her species. Then, when the public spotlight suddenly turns to her, she’ll drag him into a revolution.

The Callista Alignment is Book One in The Natural Human Saga, a science fiction space opera exploring alien prejudice, captivity, and the strength of found family. Featuring a strong female lead this emotional saga of courage and redemption will appeal to readers of The Long Way to a Small Angry Planet, The Pet Project and The Planet of the Apes.
.
Meet the cast:
The Professor – Yan Feyrsten thinks he's made a big mistake. The human he’s just bought is upending his quiet academic life. Kali won’t settle, won’t eat, won’t comply. She can’t grasp that here on Antaris, she’s nothing more than an animal.
The Naturalist – Henik Varkesen understands why. He’s imagined meeting an Earth-born ‘natural’ his entire professional life. But he realises the trouble Kali could bring—that she’s either a wondrous scientific discovery or the most dangerous human on the planet.
The Bounty Hunter – Torsta Jai knows an opportunity when she sees one. Reduced to hunting feral humans in the Derelict Zone, the disgraced police chief is looking for a way to restore her position. She realises Yan’s human could give her the political leverage she needs and will stop at nothing to possess her.
The Human – Kali is just trying to get by in a baffling alien world. She’ll start with Yan, use her gift with language to confound his expectations, and force him to reassess everything he believes. But when she is stolen away and thrust into the public spotlight, she’ll discover the truth: a restive human population has been waiting for a sign, waiting for their moment. They’ve been waiting for her.

Contains occasional strong language, non-graphic violence, and mature thematic content. Suitable for readers aged 15 and up.

Book 2, The Callista Ascendancy, continues the saga. Abducted over thousands of years, a human diaspora is spread across the cosmos, a slave species clinging to the legend of a place called Earth. This continues the story of one of them - her truth, her courage, her destiny.

Description:

War has come to the Galaxy.

The dark forces of the Neo Hegemony strike, sweeping across the worlds of the Arcadian sector and crushing all in their path. One system stands against the onslaught, the Kingdom of New Avalon. But the men and women of their expeditionary forces are trapped behind enemy lines on a besieged planet.

Losing those troops will lose the war. Their only hope? A last-ditch rescue mission led by Captain Hal Cutter and his battleship, Achilles.

Beset on all sides by lethal enemy warships, he must lead a rag-tag fleet of naval and civilian vessels across Hegemony-held space to save the beleaguered Kingdom soldiers.

In the skies and orbit, Lieutenant Jason ‘Rick’ Richards and the untested pilots of Viper squadron clash in a furious battle for supremacy against elite enemy fighters. And on the ground, Private Patrick ‘Wink’ Goble and his platoon must hold the line against a ruthless commander and her overwhelming force of battle-tested mechs until salvation arrives. All will play their part in this desperate struggle for survival against impossible odds.

The Great War has begun… Audio book available. Read by Jeffrey Kafer.
Read the epic new military science fiction series from Ralph Kern, the best-selling author of the Locus series. “A Rain of Fire, the first book in Ralph Kern’s Great War series, is a military science fiction tour de force. Most mil-SF writers seem to fall into retelling World War Two without realizing or admitting it, but Kern has embraced the inspired idea of writing an analog for the war that defined our modern world, except in a far-flung interstellar society of thousands of years in the future. It’s a daring conceit and he pulls it off with panache and skill. The characters are well drawn and engaging and the action keeps you on the edge of your seat. An excellent introduction to a universe I look forward to exploring further.”
Rick Partlow – Best Selling Author of Drop Trooper

"A vivid story, written in stunning detail by a master of his craft. This book went far and away beyond immersive--I could smell the acrid tang of the smoke and taste the blood. Truly riveting! If you haven't read Ralph Kern before, you are missing out." Jasper T. Scott - Best-selling author of Dark Space

"Ralph Kern has taken the most important conflict of the 20th century and brought it to vivid life on a galactic scale. Amidst the cool tech and epic space battles, it's the human element that truly draws you into this book. With several characters based on historical figures, Ralph grounds the story in the lived experiences of humans grappling with a world-shaking conflict. Rain of Fire is both military science fiction epic and an important act of remembrance. Highly recommended."
Scott Bartlett - Best-selling author of Supercarrier

"Searing action fuses with daring strategy and seductively dark ideology in this addictive new series from a major talent in military science-fiction."
Tim C. Taylor - Best-selling author of The Human Legion

Description:

In the heart of enemy territory, Vanti must save the day without blowing her cover... or her cool.

Security for a reality star cruising on a billionaire's space yacht should be excellent cover for secret agent Lindsay "Vanti" Fioravanti. Her boss, the famous Elodie-Oh, doesn't care where they go, as long as it's viral.

Then Arun, the ship's owner and pilot, grabs an opportunity to do business on Gagarin--a planet emerging into capitalism with enthusiasm. Getting in on the new market is a huge risk, but could offer enormous rewards. And visiting Gagarin gives Vanti the chance to recruit new informants.

But when a shipmate is kidnapped, Vanti and Arun must come to the rescue. Can they do it without exposing Vanti's secret identity? And if not, who will feed the cat?
