Operation Medusa, book 6 in the Castle Federation series, is out now!

Operation Medusa, the sixth and final book in the Castle Federation series by Glynn Stewart, is now out on Amazon.

A battered but undefeated Alliance
A war they cannot win by force
A plan to turn the tide of history!

For two years, the Castle Federation and the Alliance of Free Stars have stood against Marshal James Walkingstick of the Terran Commonwealth and his mission of conquest. Battles have been won and lost, worlds have died, and soldiers like Admiral Kyle Roberts have been forged on the anvil of war.

But the Alliance cannot win. The Commonwealth has more worlds, more ships, more soldiers. They claim their victory is inevitable. That history is on their side.

Refusing to accept the Commonwealth’s future, the Alliance embarks on a do-or-die mission to end the war in one strike. If Kyle Roberts’s plan works, the Commonwealth will break.

But if it fails the Alliance will be broken.

Oath of Vengeance out now!

Oath of Vengeance, the second book in the Vigilante Duology by Glynn Stewart and Terry Mixon, is now out on Amazon.

A mercenary with a secret past
A pirate leader with a secret mission
A clash that will shake planets

Mercenary Captain Brad Madrid has spent years building the resources to go after the man who murdered his family. His new career has benefits—but also duties and responsibilities he cannot lightly brush aside.

A new mission brings him once again into conflict with the Terror, however, and as friends and lovers alike perish around him, he realizes that responsibility and vengeance align. Neither the man he was nor the man he is can suffer the Terror to live.

Aided by allies across the planets and a familiar shadowy spy, Brad will hunt his enemy across the Solar System, chasing down a final confrontation that will shake the foundations of humanity…and fulfil his Oath of Vengeance.

Changeling’s Fealty is out now!

Changeling’s Fealty, the first in the new urban fantasy series Changeling Blood, is now out on Amazon.

 A ragged newcomer…
        With a secret even he doesn’t know
A backwater city…
        With a countdown to an explosion no one is expecting
A secret Covenant…
         And a conspiracy to break it to pieces

Jason Kilkenny is a new arrival in the Canadian city of Calgary. Unlike most newcomers, Jason isn’t looking for a job in oil and gas: he’s a half-fae changeling that wants to get away from the politics of the inhuman races.

He soon learns that despite being a supernatural backwater, the city is run by a near-godlike Wizard—and the shadows are full of unseen dangers. Jason’s here to hide, but he finds himself called to service by Calgary’s understaffed Fae Court.

As supernatural politics collide in his new home, Jason’s plan to keep his head down is shattered and he finds himself testing the limits of his meager gifts. He cannot run, he cannot hide…and if he loses, he loses everything.

Interstellar Mage is out now!

Mars destroyed his ship — but gave him a new one.
Mars drafted his Mage — for the good of humanity!
He should have known that wouldn’t be the end of it…

Captain David Rice has a new ship, a new crew, and a new set of Jump Mages to carry him between the stars. All he wants is to haul cargo, make money and keep his head down.

His past, however, is not so willing to let him go. An old enemy is reaching out from beyond the grave to destroy any chance of peace or life for Captain Rice—and old friends are only making things more complicated!

All he wants is to be a businessman, but as the death toll mounts he must decide what is more important: his quiet life or the peace humanity has enjoyed for centuries…

Terra and Imperium is out now!

The third novel in the Duchy of Terra trilogy, Terra and Imperium, is now out!
(Don’t worry, this won’t be the last we see of Duchess Annette Bond! Just the end of this trilogy)
Enjoy!

Buy it on Amazon here.

Secrets both ancient and new.
Powers great and greater—
With Terra caught in the middle

Humanity’s first colony is a project neither the Duchy of Terra nor the A!Tol Imperium can allow to fail. The planet Hope in the Alpha Centauri system has been lavished with resources and attention—but when an unknown alien force attacks the system, all of that is in danger.

An ancient alien artifact is the apparent target of the attack, an artifact older than known galactic civilization. Suddenly, the backwater colony of a second-rate power is the gathering point for a confrontation of the galaxy’s greatest powers.

Duchess Annette Bond might be pregnant. She might be five light years away. She might have another galactic power on her doorstep demanding she surrender their rebels who’ve settled on Earth.

But she speaks for both Terra and the Imperium—and the galaxy will listen.

Heart of Vengeance is out now!

For the last several months I’ve been working with Terry Mixon of the Empire of Bones series to put this together and now we get to share it with you!
Enjoy!

Buy it on Amazon here.

A pirate attack with only one survivor
A conspiracy woven across the planets
A vengeance that will not be denied

When pirates seize the inter-planetary freighter owned by Brad Mantruso’s family, he is dumped into space. Saved from death by a passing Fleet ship, he is left with nothing but his skills, a gun, and a burning desire for vengeance.

Acquiring a ship, he reinvents himself as the mercenary Captain Brad Madrid. Before he can pursue his enemies, however, he finds himself dragged into an unexpected conflict when his ship’s history draws new enemies to him.

Beset by pirates, slavers, and a woman who might be his savior—but definitely is a spy—it will take all of his skill, cunning, and new friends to claim his revenge!
