Here’s more about the book:

An empire broken by hubris
An officer raised by chance
Oaths that must be honored
Oaths that must be betrayed

Rear Admiral James Tecumseh barely survived his last mission against the Alliance of Free Stars with his reputation and life intact. Under a cloud of suspicion, he has been assigned to a quiet sector far from the front of the Terran Commonwealth’s war with the Castle Federation and its allies.

But when the Federation’s Operation Medusa cripples his nation’s communications and plummets an interstellar empire into silence, Admiral Tecumseh finds himself thrust into command of an entire fleet—and responsible for the safety of billions of innocent souls.

Enemies internal and external alike challenge the nation he is sworn to serve. Duty and honor call him to action to protect the innocent, and the Admiral and his new fleet are called to war once more.

But the darkest treason lurks where no one expects it…

The Universe of Castle Federation

The Castle Federation series is a far-future transhumanist space opera where the Terran Commonwealth, driven by their vision of Unification, are determined to bring all of human space under the rule of Earth.

They were stymied for thirty years by the forces of the Alliance of Free Stars, a multi-national force led by the Castle Federation and the Coraline Imperium.

Now, after three decades of cold war, the Commonwealth is moving again…

The series began in 2015 with Space Carrier Avalon, and ran until 2017 with Operation Medusa.

Now, Glynn Stewart’s beloved transhumanist space opera returns with Admiral’s Oath as of January 11, 2022.

When we begin…

The series focuses on the development of Kyle Roberts from a relatively low-ranking Commander, Air Group, to the architect of the operation that turns the tide of the war and the choices and sacrifices he and his comrades make along the way.

Roberts didn’t expect that a job on the decommissioned Avalon would result in both the end of peacetime and his career as a starfighter pilot. Now he has a new position in the Navy, impossible expectations to live up to, and finds himself on the losing side of a war.

Will he live up to the name of Stellar Fox, or will the Commonwealth conquer the Alliance of the Free Stars?

And when we return…

Admiral’s Oath launches the Dakotan Confederacy series and begins a brand-new adventure starring Commonwealth Admiral James Tecumseh.

After a crushing defeat of the Commonwealth that cuts off communication with Earth, Tecumseh finds himself with power he didn’t ask for.

The Admiral is forced to choose between upholding the principles of democracy, or to turn warlord in the name of stability.

2021

This won’t be a full length wrap-up. Like I said last year, my partner and I are both particularly vulnerable to covid so we’ve hunkered down as best as we can.

We lost my mother this year. Not directly to covid, but the overload of hospitals in her region due to people refusing to take it seriously was a huge factor. My sympathy and tolerance for covidiots is now less than zero. Be warned.

And as a final capstone to the year, we’ve discovered that our house has serious water damage and mold due to errors in construction. We’re out for six months while a team basically strips it down to the frames and rebuilds it from scratch.

So yeah. It’s been a stressful year.  I’ve written seven novels and a novella and published, amusingly, the same number of each (there is overlap, but the novella I published in 2021 is not the one I wrote. That’s coming out in February).

  • Equilibrium (January 2021) – Book Three of Scattered Stars Conviction.
  • Excalibur Lost (February 2021) – stand-alone novella.
  • A Darker Magic (March 2021) – Book Ten of Starship’s Mage, the first book in the Mage-Officer of Mars arc with Roslyn Chambers
  • Eyes of Tomorrow (April 2021) – Book Nine of Duchy of Terra and the final book of the series. (Also the last book in an nineteen-month run of monthly releases)
  • Drifter’s Folly (June 2021) – Book Four of the Peacekeepers of Sol
  • Fortitude (August 2021) – Book Four of of Scattered Stars Conviction.
  • Mage-Commander (September 2021) – Book Eleven of Starship’s Mage
  • Evasion (November 2021) – Book One of Scattered Stars Evasion (the second series in the setting, though Conviction is continuing)

I believe we started simultaneous audiobook releases with Evasion and will continue with Admiral’s Oath, the first book in the new series in the Castle Federation Universe. This requires some careful timing with our audiobook partner, though, and I lost several months’ of work with my mom’s illness.

But the only way to go is forward, one step at a time, one word at a time.

I hope everyone is staying safe and having a wonderful set of holidays, whatever you celebrate.

Happy reading!

A Question of Faith, a Castle Federation Novella, Available Now

A Question of Faith, a novella prequel set in the Castle Federation universe, is now available on Amazon! Taking place before the Castle Federation series, this sets up the longstanding cold war that sparks in Space Carrier Avalon.

Here’s the cover copy:

Two star nations struggle for primacy

A protectorate of both left defenceless

A call for help from any who can hear

The Castle Federation and the Coraline Imperium have built pocket empires on the fringe of human space. Tiny by the standards of the behemoth Commonwealth born of Terra, they remain unchallenged in their own sectors—but their fleets watch the border between them with careful eyes.

When the Boudicca System’s only battleship is ambushed and destroyed by forces unknown, their leader calls for help from the Federation and Imperium alike. Admiral Darius Moonblood of the Castle Federation takes a fleet to Boudicca to answer that call, believing he is walking into an Imperial trap.

It will fall to Admiral Moonblood to either start the war Castle and Coraline have feared for years or find a different answer to the conflict looming in Boudicca.
