A space fleet in shambles. A captain facing annihilation. There's never been a better time to play dirty…


Lieutenant Commander Cohen is furious. After his admiral's questionable tactics decimate all but two of their ships, Lt. Com. Cohen needs to get back to New Bristol in a hurry. But with a damaged hyperspace function, the remaining vessels are sitting ducks for the hungry, ruthless enemy…

To repair his ship, Cohen must engage a mysterious asteroid-based faction in a trade that could make or break the war. Carrying out insurgent missions on their ally's behalf, the entire plan rests on an impeccable battle strategy and just one tiny ship.

Can Lt. Com. Cohen survive the day or will the Deathless finally get their revenge?

About the author

Jon Evans

16 books9 followers
Jon Evans was born in Portsmouth, England and has worked in a fabulously dull series of jobs, none of which constitute a career. While doing these jobs the dream was always to become a writer and there were many false starts and unfinished projects.

With his brother James, he writes military science fiction in the Royal Marine Space Commandos universe. With the launch of Fleet in April 2021, there are now six books in the main series beginning with Commando which kicks off The Deathless War. They're also (slowly!) publishing a series of short stories about Marine X a.k.a. Ten - a fan favourite character with a colourful past.

With co-author Paul Teague the brothers have the By Strength and Guile trilogy, written in the same universe and time period and dealing with a special forces mission to combat a new foe, who inconsiderately reveal themselves while The Deathless War is raging.

Thieftakers is the first book in his renaissance fantasy series that will explore the life and adventures of a group of outsiders, assigned to the least desirable Watch posting in their city. Edrin Loft has plans to revolutionise the City Watch of Kalider and must prove his methods if he's to make headway. The Thieftakers are a rough bunch of misfits, whose only role is to chase the very dregs of society, where other members of the Watch fear to go.

The Edrin Loft Mysteries will be an ongoing series of novels and novellas based in Kalider, once the capital city of what is now known as The Shattered Empire. Once the series is well underway, there will be an epic fantasy series that deals with events on the macro scale, affecting the whole Shattered Empire. Currently this series is on hiatus while Jon works on the military science fiction series, but he intends to resume it once time permits.

He now lives in Cardiff, where his surname fools people into thinking he's a local.

Another victory

Great follow up to the first 3 books. Don’t want to spoil anything. But a great mix of personalities working together to achieve victory. Can’t wait for the next book and learn more about the marines of Sol and their new allies. And more about the standout Marine X and what he does next.

This has been a good series although there is a disturbing trend after the first book. The two following books have CPT Cohen strangely incompetent at the beginning but brilliant by the middle of the book. Not sure why.
Also, if an Admiral loses a fleet in battle what Navy puts him back in command of a second fleet with no inquiry?
Still a pretty good story.
This entire review has been hidden because of spoilers.

This is my favorite book so far. I like the addition of new species and worlds and the feeling of increased risk. (It didn't seem very risky when everyone just gets to upload into a new body if/when they die) Anyway, more of X is always good and I pretty much just one a whole book about him. Looking forward to the next book.

A JE./JE. SYFY. Novel (TRMSCB - 4)/A Space Battle

JE./JR. have. penned the fourth novel in the RMSCB series, which contains a space battle between two important factions one to each side in the well known conflict. Two Space Armadas are closing to engage in a Space War to end the conflict between humans and the alleged lizard personnel. This fourth novel has done a superb job setting up the fifth novel of the series or a parallel war footinng between opposing firces. This is an excellent read for the genre.....DEHS

Decent story

Gunboat was the 4th novel, if you like this kind of story start at the beginning, you’ll learn about the people & tech that is continuing through this series.
Not the best of the set, but I will definitely buy & read the next book.
