A missing scientist, a lost bioweapon, and just one flimsy lead…

Billy Firebrand and his dysfunctional crew of mercenaries are on the trail of the greatest mystery they've ever faced. Only when they arrive on the resort world of Calypso, expecting to find some answers, they uncover nothing but more questions.

Now, both the ship and the crew are coming apart at the seams, and it's all Billy can do to keep them together while somehow tracking down one of the deadliest weapons ever devised.

Gans of The Worst Ship in the Fleet and Rogue Agent will love this new series full of swashbuckling adventure, witty banter, and plenty of sci-fi fun. Tag along with this crew of has-beens as they redefine what it means to be heroes (and not always in a good way). Set in the fan-favorite universe of Dumb Luck and Dead Heroes, you don't need to have read that series to fully enjoy this action-packed series.

Also known as The Kaelen Extraction Book 2.

Skyler Ramirez

Skyler Ramirez’s imagination knows no bounds, and their work within the science fiction genre proves it. Drawing readers into expansive worlds full of political intrigue, high-stakes conflict, and unforgettable characters, Skyler has quickly carved a unique space in the literary landscape. With a passion for storytelling that blends intense space operas and intimate character-driven narratives, their writing taps into the universal themes of power, loyalty, and survival.

Skyler’s journey as an author began with a fascination for the farthest reaches of space, where humanity’s reach often exceeds its grasp. This love for sci-fi grew over the years, fueling a desire to create worlds that feel as real as the one we inhabit, yet full of possibilities we can only dream of. With each new novel, Skyler expands upon intricate galaxies and star nations, blending fast-paced action with thought-provoking philosophical questions.

The A Star Nation in Peril series, one of their most notable works, is a powerful example of Skyler's ability to merge deep world-building with dynamic, relatable characters. It’s a story of political unrest, shifting alliances, and the tension between personal and collective survival—offering readers not only an adventure through the stars but also a reflection on the nature of power, loyalty, and betrayal.

For Skyler, writing is more than just a creative outlet—it’s an exploration of what it means to fight for something greater than oneself. As they continue to weave complex plots and characters, their works resonate with fans who crave multifaceted narratives that explore the human condition in the context of expansive universes.

When they aren’t crafting galaxies and star systems, Skyler can be found in the midst of a good book, exploring new genres and ideas to inspire their next stories. Their writing style is as much a reflection of their curiosity about the universe as it is a tribute to their love for the unknown, always pushing the boundaries of what’s possible while keeping readers grounded in the emotional truths of their characters.

Skyler Ramirez’s works promise a journey—one that’s as much about discovering new worlds as it is about discovering what it truly means to be human in the vastness of the universe.
