Can a stubborn miner and a gruff cyborg ranger survive the dangers of Mars—and their growing desire?

Mattie is perfectly happy on her isolated mining claim, thank you very much. She and her cybernetic canary Sylvester are doing just fine—no matter what the big, grumpy cyborg responsible for her territory seems to think.

J-418 takes his job as a ranger very seriously. Frequent checks on the stubborn, annoying—and ridiculously adorable—woman living on her own are just part of his job. They certainly aren’t because he actually enjoys his encounters with the prickly little female.

When danger forces the two together, they make a series of startling discoveries, not the least of which is an unexpected passion. But life on Mars is about to change - for everyone!

Each book in the Cyborg on Mars series can be enjoyed as a standalone romance. This sweet and steamy science fiction romance is intended for mature readers. A version of this story was previously published in the Pets in Space 9 anthology.

Cyborgs on Mars

The series

Full series details →

On the scarlet plains of Mars, survival is more than a test of strength, it is a measure of what it means to be human. Engineered from the remnants of war, the cyborgs of Mars were designed to endure isolation, harsh landscapes, and the weight of their own power. Decades later, their world has become both prison and sanctuary, where the line between machine and heart grows ever thinner.

Read full series description

Everything changes when humans from Earth arrive, sparking desire, conflict, and the chance for connection that the cyborgs long thought impossible. As loyalties are tested and secrets unravel, each encounter forces them to confront the emotions they suppressed for survival and the freedom they never imagined they could have.

Blending high-stakes science fiction with romance, the series immerses readers in a Martian colony filled with danger, intrigue, and passion. The stories explore identity, resilience, and the cost of freedom in a world where love may be the ultimate rebellion.

What Risingshadow readers think about this book

9/10

This was the first book from the Cyborgs on Mars that I have read and I enjoyed reading it and getting to know J-418 (Jeb) & Mattie. I also really liked Mattie's cybernetic canary Sylvester and Jeb's cybernetic horse Trojan, they were a really fun pair to lighten the mood sometimes. I always enjoy reading Honey Phillips' books and look forward to reading many more in the future.

I received a free advanced reader copy of this book from the author and am voluntarily leaving a review.
