Halberd #3
True Allegiance
The end of the war should bring peace, right?
In the midst of what should be a time of celebration, Halberd is called to duty to respond to a surprise threat. His task force of three Royal Navy ships that employ advanced technology is needed to counter an attack in a non-aligned system. Taking advantage of Halberd’s absence and a Royal Navy weakened by war, the other inter-stellar superpower, the Chinese Republics, invades the Commonwealth.
Provided by a traitor with the technology that provided the Royal Navy with the edge it needed to win the war with the Rodinan Federation, the Republican navy obliterates a good chunk of the fleet, and nearly wins the war in the first battle. Outnumbered, the Commonwealth’s survival is in doubt. The Royal Navy is forced to bring warships out of mothballs in order to mount a defense.
Hope do you keep your hopes alive in the face of such losses?
True Allegiance is the third book in the thrilling Captain Halberd Series. If you love classic military sci-fi with compelling characters, innovative tactics, and explosive space battles, you'll be captivated by John J. Spearman's fast-paced adventure.
Join HMS Cumberland on her maiden voyage and discover what it truly means to lead, to fight, and to win against impossible odds.

The raw emotion you feel at the end turns this from a good book into a great one
The raw emotion you feel at the end turns this from a good book into a great one. I will not spoil the story for readers starting this story. This book is a masterpiece in its genre. It has all the space battles and derring do that you would expect but then it takes the first three of the trilogy to lead to an emotional rollercoaster that left me feeling breathless.

rare
This is one of those rare space operas that takes on a solid ride beginning to end. It is filled with characters that become real with complex personalities. It takes you through emotional developments that you can understand and relate to.

It's always great to reading these books, Captain Halberd...
I am very much focused upon turning the pages of these books.
Realizing I'm reading faster as time takes me through book 3 now.
Hard to slow down and make it last longer !
Great characters and a very good story line with humor and romance.
Warning though !
The unexspected - is exactly that.... Unexspected !!
But I have found these books very rich in the relationships of true friends who hold to doing what is the right thing to do regardless to any cercumstances....
Love this series much more than I expected.....
Going in to open book 4 now....

Jonah's success continues personally as well as professionally. Unfortunately, there are now two targets for the bad guys to pursue. Weapons development now requires rethinking their tactical planning and use. Jonah and his fellow admirals manage it well for victories but casualties mount and often can include long-time friends. One enemy falls but the remaining Chinese worlds become a very dangerous threat. Fortunately, episode four is available so I can continue this very readable ad interesting story.

Started Skimming Book 2, continued thru 3
I should have stopped after first book, but I continued and regret it. Hence the 3 stars that it doesn't deserve,
Bottom line: Reads like a teen male romance fantasy that has uneven pacing, dull action, short on tech n mil and spends more time on fashion, pomp and circumstance. MC isn't very engaging and author is Inconsistent with MC's so-called 'leadership' and tactical skills.

Best of the series so far
This series has grown on me. The battles are still told clinically, but less so than in the earlier books. In fact, there is a whole world of emotion being explored in the non-battle portions, and the characters have grown significantly. On to the next book…

Good read.
This was also a very good book , it kept me up late just to read on to see what would happen next. The book was full of space battles and a few new upgrades in technology that put the good guys ahead a little but they were still up against a good enemy that had studied them well and in the end heart brake happened . On to the next.

Excellent series
This series does leave u hanging but also has a good continuance possible , it is spell binding and a tearjerker if you are at all emotional. I thoroughly enjoyed it and am looking for more from this author.

Good storyteller
I’ve read several books by this author. Once I adapted to his style of writing I found myself thoroughly enjoying his stories. Not too deep, not too political, just right on several levels.

A wonderful combination of military, politics and interpersonal relationships
Take Aubrey and Hornblower and add much more complexity.... in a Space Opera.... Wonderful stuff. The meshing of current events in a 1000 years from now environment works.

A not total surprise but a little disappointing.
The story is again full of non-stop action and lots of tender moments. The characters continue to become more interesting. The politics are getting more complicated. The plot gets more twisted. A very fun read.

Halberd series
This series has lots of action and intrigue. The complexity of war is apparent at the level of Admiral. Spearman brings out the complexity without getting bogged down in the details. I enjoyed this book. I was a nice fresh viewpoint.

Excellent book
What John Spearman did in this book Was a great thing and great writing And in the main relationship between the hero and his wife I feel he must be talking about his own wife and how he would feel if he lost her the last part of this book is a tearjerker

Amazing!
I thoroughly enjoy John Spearman's writing. It's energetic, emotional, politically aware and human. I'm about to start the next book in this series right away.

3 stars. Simplistic and dry writing. Comes across as if you're reading a 3rd person diary. Or perhaps a history text. Still, there is plenty of space warfare action, so there is that.

I began to think that the author was running out of ideas, so he did what every Soap Opera producer does when the rating start to flag, he kills off one of the main characters.

So we'll written
This book was an unexpected emotional rollercoaster. The character development is on point, you're on the ride right next to them.
