Admiral's Oath: Dakotan Confederacy Book 1 (Castle Federation 7) Kindle Edition
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…

- Reviewed in the United States on January 11, 2022I received an advance copy in return for an honest review!
This is one of my favorite books of Glynn's in the past few years. We get to see another side to a (probably) familiar universe - because you've already read the Stellar Fox books, right??? If not, DEFINITELY read those, but you don't NEED to before you read this book, it stands on its own just fine.
I wasn't ready to enjoy this book, because the Stellar Fox is second only to Damien Montgomery in terms of my favorite Glynn Stewart characters. How could I actually LIKE one of his adversaries?
But if you expect Glynn to do anything in vanilla manner, you don't know Glynn. Even in subtle ways he manages to bring you to a different outcome than you expect. Even expecting twists, he surprises you!
I wholeheartedly recommend this book.
- Reviewed in the United States on September 17, 2022I love the world that Glynn Stewart has created here and in previous books. Simply adore it. It captures my mind, my imagination. So I came into this book expecting great things. And overall, I was a little disappointed. I think that Stewart grapples with some big issues, largely successfully, but was unsuccessful at creating characters as generally likeable as in the previous series (which, just so you are aware, you do not need to read to start this book). This was an honorable attempt to keep a successful and interesting universe alive, and I will read the next book, but it just didn't have the same heart as previous entries. I miss the Stellar Fox.
- Reviewed in the United States on January 12, 2022I did not get an ARC copy of the book, just look forward to Glynn Stewart's work and read pretty soon a as they are released. We met Admiral James Tecumseh in the previous series at the end of the war and learned he was an honorable man. Now we see him and the Commonwealth as they deal with defeat and the changes brought on by loosing FTL communications. The plot is interesting and intriguing. The new characters are well drawn and real. This is a good book, really well done, and I look forward to the sequels
- Reviewed in the United States on May 28, 2024Good story teller with plenty of action. A very fun read!
- Reviewed in the United States on January 16, 2022I loved the Castle Federation series and was very sad when it ended. That it came back is amazing. The new world Glynn has turned this series into is pure genius and entertainment! This was a quality of work and writing that has stunned me and has me very excited for what comes next. Glynn is very talented, but I think he has outdone himself with this book. Highly recommend! Reading the previous series will help understand the world rules, but it not nessessary to enjoy this book.
- Reviewed in the United States on December 5, 2023This is different. After six books in the series,spoiler alert, we switch sides and the enemy now becomes the protagonist. Yes, we know him from before as an honorable man on the other side,but still the enemy for six books. Interesting,but it is also true that this book lives of the great stories of its predecessors,since 90% of this book can be summed up with : administrative and organizational problems for an Admiral after a big bang. Of course I will finish the series, having invested so much time already. 4 stars 7 books in is still pretty great.
- Reviewed in the United States on February 25, 2022This, the first book of this series, views the Terran Commonwealth perspective AFTER the major strike by the Alliance of Free Worlds on the Commonwealth communications network. A very entertaining tale with great character insight, exciting storyline and all the action one could hope for! Author Glynn Stewart has indeed spun one masterful tale - a MUST read!
- Reviewed in the United States on September 1, 2022To be perfectly honest with you I really like how you wrote the story. I'll be honest I didn't need to read any of your other books in the world that you've created to actually know what was going on in the story.
And the fact that you subtly explained it and then you left characters and names of people that I already knew were there and events that happened really made enjoying all of your books that much better.
He did a really good job on this one.

5.0 out of 5 stars The Stellar Fox Universe continues...
A new novel delivered in the style and attention to detail I have long loved and come to expect of one of my favorite authors! We reconnect with some known friends from previous books of this series and continue to learn what future awaits the Terran Commonwealth as their choices come home to roost.
This is the tale of a man whose ironclad morales and principles form the rock that fate manages to get him caught between so many hard places... Brilliant!

5.0 out of 5 stars A triumphant return to the Castle Federation Universe
I binged Admiral's Oath over a single day. The book was great on its own merits, with diverse characters facing ethical dilemmas against a backdrop of a detailed sci-fi future where humanity has spread out to the stars, but the Terran Commonwealth (centered on Earth of course) is intent on Manifest Destiny and is conquering the frontier colonies "for their own good".
The main character was previously a supporting character (well, antagonist) in the earlier Castle Federation books, and Admiral's Oath picks up at the end of the previous series after the events of Operation Medusa destroyed the FTL communications of the Terran Commonwealth.
This is vintage Glynn Stewart, and if you liked the earlier Castle Federation books (highly recommended) or his other works such as the Duchy of Terra or Scattered Stars series, you will enjoy this.
And if you have already read the Castle Federation series, you'll probably end up re-reading it after Admiral's Oath if you are like me.

5.0 out of 5 stars Great start
I bought this book originally purely due to it be written by Glynn Stewart. I have bought and enjoyed every book he has written and was very pleased when it turned out to be a continuation of the Castle Federation books. But from the other sides perspective.
This book was as readable as all Mr Stewarts books and set up this next series brilliantly. Although you could read this without the need to read the 5 original confederacy books, you will enjoy it more if you do I believe.
Some new characters and adding to some known ones and I look forward to the next book.
- Frank HellerReviewed in Australia on August 1, 2022
5.0 out of 5 stars Solid
Very nice. Thoroughly enjoyed this book. Looking forward to the sequels.
- PierreReviewed in France on March 19, 2022
1.0 out of 5 stars Lack of inspiration
I am a fan of Glynn Stewart, but this book feels like it is a rehash of several previous book with the same plot with characters with different names. Plus this doesn'nt bring anything really new to the table, why start a new serie for that ?
