About The Book

Author Direct Exclusive Illustrated Edition

Jayden wants to do three things: find the rebel base, collect his reward, and never once let himself care.

Dispatched to locate a rebel settlement on the electromagnetically hostile world of Osivirius, Jayden Seymour crashes instead into a valley that should not exist: biodynamic orchards, hand-forged tools, and a society where no one is above serving the next meal or standing the next watch. This is not a rebel cell. It is a living argument against everything the colony was built to be.

But it’s the Masu that make the argument impossible to dismiss. Flying cats the size of small aircraft, they share a fungal mind-link with humans that opens up a wordless exchange no colonial education prepared him for. They do not ask to be trusted. They show him what trust feels like.

As the slow architecture of suspicion between Jayden and the woman determined to despise him begins to shift, so does everything he thought his life was for, and two people who built their entire existence around around half-truths slowly learn they're not so different after all. The cats have already decided, the only question left is whether Jayden has the courage to agree.

For fans of James Cameron’s Avatar and the ecological richness of Ursula K. Le Guin, this hopeful, slow-burn science fiction novel delivers lush alien world-building and a romance forged in shared grief rather than manufactured tension. What is at stake is not survival, but something far harder: the courage to choose a life that actually means something. This is soft science fiction at its most hopeful, with a slow-burn romance at its heart and giant flying cats who do not ask for your loyalty so much as remind you what it feels like to be whole.

Click ‘BUY NOW’, crash-land on Osivirius today, and enter a world that might not let you leave.

“A lushly imagined, and hopeful serving of adventure filled with heart, humanity and flying cats. I loved it!” — Trent Jamieson, award-winning author of Stone Road, Day Boy, the Death Works Series, and the Nightbound Land Duology

“Son of Osivirius surprised me with its heart. Beneath the adventure and the danger, this is a story about belonging and trust, and how hard it is to let go of fear in order to live freely. I would recommend this book to readers who enjoy science fiction that balances action with deeper themes, especially fans of Avatar or The Left Hand of Darkness. It’s also a great pick for anyone who wants an adventure with strong characters, a lush setting, and deep ideas. 5 Stars. ”

Literary Titan
