The Genevians are at war with Nietzschea
…and they’re losing.

In a last-ditch hope, the Genevian mech program was founded. Its goal to augment humans into cyborg fighting machines; mechanized warriors sent to hold the front lines against an enemy that was storming a hundred worlds.

Yet few wished to undergo the brutal process, and so criminals were used, their minds enslaved by control chips and obedience enforced through Discipline.

The Genevians spent their mechs against the Nietzscheans with little care, eventually struggling to find enough bodies to convert into fighting machines. Quotas were set in the courts, prosecutors and judges paid off to ensure that even the most benign offenses would see the perpetrator end up in a mech factory, rights and mind stripped as much as body.

Rika is one such victim.

Forged into a second generation scout mech, she is sent to the front lines where she serves with distinction, crushing countless enemies beneath her clawed feet.

But, despite giving everything she had, Genevia still loses the war, and Rika is abandoned.
Now she slings cargo on Dekar, little more than a human loading machine, struggling to keep ahead of the slow breakdown of her mechanized body.

Until someone makes her an offer she cannot refuse. An offer that will see her rejoin the fight—whether she wants to or not. Rika will have to summon a strength she never knew she had to bring about the victory that she once thought was lost.

Get Rika’s Marauders today and follow the ultimate rags-to-riches story, where one woman rises up and saves not only herself, but her people.

This omnibus volume contains all 7 books in the Rika’s Marauders series, as well as two novellas: Rika Mechanized and Rika Crucible.

A wonderful story!!! (Praise for Book 1)
This is a terrific sci fi novel. The characters are well imagined and fleshed out. The plot is rather unique and full of both action and emotions. D D Hart has hit a homerun with this one and I can hardly wait for the sequel.
(Verified Amazon Review)

Goes farther than I expected (Praise for Book 2 - Concluding the series)
Worth coming back for the second book. Solves issues in Hvar and then moves on to much wider terrain. Great battles and bold ideas.

Demons, super warriors, prophecy, treachery and death awaits as they stumble across the true origins of mankind.

This knowledge, this one truth must return home, must get to Earth - no matter what the cost.

A message from the stars offers humanity an escape from our harsh origins deep within a region known as "Cruel Space" by the rest of the galaxy. Earth's nations unite to construct the Dauntless—Earth's first interstellar craft. Its mission: to journey to the world of Centris and establish formal contact with the enigmatic Galactic Council. Unsure of what to expect from the wider galaxy, each crewman was trained to be a peerless warrior, armed to the teeth and ready to fight for all humanity.

However, what they encounter was far from their expectations. Instead of monstrous beings, they find a galaxy dominated by... Women. Humanity's nearly equal ratio of male to female births is an anomaly. In a society where females far outnumber males, opportunities abound, from unimaginable wealth, to incredible danger, on worlds where immortality is a lifestyle choice and love is available on a scale beyond human comprehension.

On this grand cosmic stage steps Jerry Bridger with a secret mission of his own—to transport a vital piece of Earth's legacy to the stars for the future of humanity. As he navigates through amorous pirates and perilous naval engagements, Jerry will fight like hell while forming bonds in the most unexpected of places, all to forge a future in the stars.

Of Dog, Volpir and Man; a story of spacefaring adventure, high technology and higher hemlines!

Early Reviews:

"I can't believe I'm on 3 hours of sleep in the last 48 hours because of this story."
- Paddydeen, Reader

"Oh are you done reading and ready to be a human again?"
- Paddy's Wife, Mildly Irate Spouse of Reader

"It's like Star Trek had a baby with an unpublished Tom Clancy scifi novel, then some mad man spliced in a harem romance from the mirror universe where everyone's a mature, sensible adult and actually trying to make a multi-member marriage work for the betterment and happiness of everyone involved. It's weird. I like it!"

Physics doesn’t negotiate. Neither does she.

Twelve years ago, a Polish colony found an alien warship in a debris field. Now every superpower in human space wants what they reverse-engineered.

On the frontier, Polonia Prime is a small, underfunded nation with one unforgivable advantage: hybrid alien drive and weapons technology that can rewrite every fleet doctrine in the Hyades Cluster.

Lieutenant Commander Maria Roszak earned her command through tactical competence, not bloodline or politics. Her destroyer B?yskawica is a relic on the outside, retrofitted inside with forbidden Bubble-drive systems, railgun batteries, and point-defense grids that skate the edge of physics. When a Zenith Caliphate carrier strike group crosses the border to seize Polonia’s secrets, Maria finds herself outnumbered, outgunned—and no longer sure her own side is playing straight.

Every time the enemy finds her faster than they should, suspicion grows. If she’s right about a leak in her own chain of command, exposing it could destroy her career and her ship long before the Caliphate does. To keep her crew alive and her nation independent, Maria must turn debris fields into weapons, doctrine into a disadvantage, and an obsolete destroyer into the sharpest blade in Polonia’s arsenal.

In a battlespace where Newtonian recoil, delta-v budgets, and railgun kinetics decide who lives, one captain’s brain is the only shield her people have left.

For readers who love:

Hard-science military space opera with real-physics combat (Bubble-drive micro-jumps, railguns, missiles, point defense, no magic)
Underdog nations, carrier strike groups, and destroyer-captain tactics under political pressure
Competent female officers, gritty tone, and respect for military professionalism
Series like The Lost Fleet and The Expanse, where brains matter more than bigger guns
