She’s the mission. He’s the monster everyone fears. His claim might destroy them both.

Dani

I came to Radin chasing a miracle cure hidden in a flower. I never expected to become prey. Days of captivity leave my empathic senses burned out, my power little more than an ache beneath my skin.

Then Jaxin arrives, silent, shark-eyed, built for violence. When the rescue goes awry, he hauls me over his shoulder and runs. Alone in Radin’s humid jungle, survival means pressed bodies, shared breath, and heat that has nothing to do with the heat of summer.

As my empathy recovers, I feel what he hides. Control layered over hunger. Possession strangled by discipline. A truth he refuses to face: he feels more than he’s allowed.

Jaxin

Emotion is forbidden. My people, the Rummicaron, suppress it for a reason. But the jungle strips restraint bare, and my true nature claws its way to the surface: to claim, to protect, to possess a mate.

Dani doesn’t just tempt me, she awakens something ancient and dangerous. As Radin’s giant closes in and a crime lord tightens her grip, I must choose between duty and instinct.

And if I choose wrong, Radin will kill us both.

This is a standalone novel and the eighth book in the Monster Mercenary Mates series. This sci-fi monster romance features a not-so-emotionless, shark-like alien mercenary, a gifted empathic scientist, and a steamy HEA.

The series

Full series details →

In a world where danger lurks around every corner and power comes with a price, Monster Mercenary Mates introduces readers to a universe where mercenaries aren’t just soldiers—they’re monstrous beings bound by loyalty, honor, and passion. This is a series where forbidden desires collide with fierce battles and dangerous stakes, offering a heady mix of action, romance, and unrelenting suspense.

Read full series description

Set in a gritty, high-stakes world where mercenaries are both feared and revered, Monster Mercenary Mates immerses readers in a universe where combatants aren’t just human but monstrous, each with their own unique abilities and darker sides. The mercenaries are powerful creatures—shapeshifters, beasts, and warriors—who walk the line between heroism and destruction, their loyalty to each other being their greatest strength and their deepest vulnerability.

The series doesn't shy away from complexity. As these mercenaries face daunting missions and unravel dangerous plots, they also wrestle with their own identities and emotions, making their journeys deeply personal. For every fierce fight, there’s a passionate connection that’s built on trust, raw attraction, and the undeniable bond of being mates. The chemistry between characters is electric, and the romance is far from predictable. Every relationship is as complicated and nuanced as the world they navigate.

What makes Monster Mercenary Mates stand out is its ability to blend intense world-building with multi-dimensional characters. Readers are drawn into a setting where power, betrayal, and survival are ever-present, and yet, amid all the chaos, there is always the hope of finding something real—whether it’s a love that transcends boundaries or the camaraderie forged through battle. The monsters in this world are not just scary—they’re compelling, deeply human in their struggles, and utterly irresistible.

With sharp, engaging writing, Monster Mercenary Mates promises to keep readers on the edge of their seats, eager to see what happens next. Each installment weaves a tale that explores not only the battles fought outside but the ones waged within. It’s a series about survival, loyalty, and the monsters within us all, and once you enter this world, you won’t want to leave.

If you're looking for a series that mixes steamy romance with high-action adventure, Monster Mercenary Mates offers the perfect escape into a world where nothing is what it seems and the only thing stronger than their monstrous nature is the bond they share.

10/10

I really enjoyed this newest addition to the Monster Mercenary Mates series and getting to know Jaxin & Danitalin. Seeing how the relationship between Jaxin & Dani grew as the story unfolded was entertaining and I also liked the Radin Giant Taktak that they befriend. I look forward to reading the next book in this series.
