This is probably one of the least convincing McGill episodes: the story is very disjointed, the stakes are confused, there are a lot of inconsistencies in the story. Whole sections of the plot are completely abandoned along the way. (the revolution? magic tapper reappearing?).
It is as if the author(s) had thrown into the pot all the usual themes of McGill's adventures with a thread, and then someone had lost the thread. Suddenly the reader has nothing left but soup.
This impression may have arisen here and there in previous episodes, but here it is particularly obvious.
It's still entertaining but in the end I don't quite understand what the author was going with. Does he know it himself? Probably not.
I love this universe, I love this characters, but I need real STORIES.

“Green World” is the 15th book in the Undying Mercenaries series by B V Larson, a USA Today bestselling author of military science fiction. The series follows the exploits of James McGill, a soldier of Legion Varus, who fights for Earth in a galactic war against various alien races. McGill is known for his cunning, courage, and charisma, as well as his tendency to bend the rules and get into trouble.

In this book, McGill and his comrades are sent to Green World, a planet in the Skay sector that was previously colonized by Earth. There, they discover a rebel base that plans to attack Earth and retake all the planets that humans have conquered. McGill stumbles onto the rebel camp and triggers a chain of events that leads to a full-scale war between Earth and the Skay, as well as other rival Galactics. McGill has to use all his skills and luck to survive and save Earth from destruction.

The audiobook is narrated by Mark Boyett, who has voiced all the previous books in the series. Boyett does a great job of bringing the characters and the action to life, using different accents and tones to distinguish them. He also captures the humor and sarcasm of McGill's narration, as well as the tension and excitement of the battles. Boyett's voice is clear and engaging, and he keeps the listener hooked throughout the story.

The book is a fast-paced and entertaining read, full of twists and turns, humor and drama, and sci-fi action and adventure. Larson has created a rich and diverse universe, with various alien races, cultures, and technologies. He also explores the themes of loyalty, friendship, honor, and politics, as McGill and his friends face moral dilemmas and ethical challenges. The book is also full of references and callbacks to previous books in the series, which will delight the fans and reward their loyalty.

However, the book also has some flaws and weaknesses. The plot is somewhat predictable and formulaic, following the same pattern as the previous books.

Overall, “Green World” is a fun and enjoyable audiobook for fans of the Undying Mercenaries series and military science fiction in general. It is not a masterpiece of literature, but it is a good way to spend hours of entertainment and escapism. It is recommended for listeners who like action-packed and humorous sci-fi stories, with a likable and witty protagonist, and a lot of alien carnage.

This one felt like it skipped around a lot at the beginning. The plot just kind of jumps from one thing to the next, picking up and dropping threads. By the end of it I didn't feel like anything happened. The fighting was good. The characters are still good. But the plot just felt completely lost.

Humm, other than the water, I'm not sure what they cover to this book is supposed to indicate. There was not underwater station like shown on the cover as far as I remember. Green World is a water world with small islands here and there. Our main character, James McGill has passed through here before. He didn't get to see much of it, but this time he's almost stuck here twice. They last time he leaves here, he's dead!

If you remember, James McGill is a Varus Legionnaire. He also has the rank of Centurion which puts him in charge of about a platoon sized unit in the Legion. At the start of this book, Legion Varus has stood down with nothing much going on. James has been staying with a lady friend, as usual, but it's not Galina Turov or Tribune Turov, his boss and on again/off again lover! But now, that same Tribune Turov was urgently trying to contact James with a new assignment. He, as usual, was ignoring it as long as he could, but since he was pretty bored with doing nothing, he finally answered the call.

And his new assignment was going to suck big time. Someone has been stealing a lot of Legion supplies and equipment. These shipments were coming in to the docks by ship and then disappearing. Tribune Turov wanted McGill to go and investigate what was going on and to put a stop to it! McGill objected to the assignment indicating that it wasn't a job for a Centurion and he was not an investigator. Galina told him that he was going to do as she said because she didn't have anyone else available. She also told him that the previous investigators assigned to this job had disappeared! James didn't like to hear that.

So, James McGill begins his new job as an Investigator on the docks of Central City. He finds a ship loaded with supplies and equipment and then he finds a whole lot of trouble. While he does identify the smugglers that are taking the stuff, there are way to many of them for him to kill immediately, so he manages to escape by getting one of the workers to teleport him to where ever they are sending all the supplies and equipment. He's in kind of a hurry since about forty guys are gunning for him so he doesn't really check to see where he's being sent. That's how he winds up at Green World this first time.

As the story goes, you'll find that James runs into a Claver, the female type, named Abigail Claver. She once had the hots for James, as did most females until they got to know him, but now she's back with her clone brother Clavers running this smuggling operation. She's definitely not in charge. This is where James runs into a few people or aliens he's known before. One is Maurice Armel and the other is a saurian named Raash. James gets to meet these two after Abigail shoots him dead! Yes, dying in these stories is something people do all the time and rather frequently. James usually manages to keep from dying very often, but in this book he seems to accomplish this rather dangerously too often. Each time he dies, he runs the risk of not being revived or permed.

Anyway, James stirs things up and the entire Legion gets involved. The only problem with this is that it's a trap both for the Legion Varus and Earth. While James is concerned with him and his Legion friends dying during this mission, he is more than agitated when he learns that his daughter, Etta, has been killed back on Earth. She's not a Legionnaire and doesn't have the normal backup required for revival as does James. So, that's where his attentions are focused during the latter half of the book. He's bound and determined to bring Etta back one way or another.

I like these stories because they have a ton of subtle humor not found in a lot of my military sci-fi books. James is quite a character and the relationships he has with the people around him is remarkable to put it mildly. And, for a book to talk about getting killed over and over again as though it's a normal thing shows you what kind of strange book this can be. Still, it's an accepted part of being a Legionnaire in these books. I like them and hope to see more come, but fifteen books in one series is quite a lot. I still think there can be more yet to come.

Didn't like this one as much.

However, it was still good and exciting. I've enjoyed the entire series. But I must admit, even in the world of science fiction, you run out of steam. This story is kind of doing that now. It's almost time for it to end, but that's okay. Mr. Larson is already a 'writin' fool'. Good Lord, I've read at least 30 of his books. He's got plenty of other ideas to lay out in his career. So I'd like to see Good Ole James McGill finally wind down and be able to relax. Once again, still enjoy the characters.

Story line was good

The story is really good But in My opinion, its time for the MC to find a woman that is loyal to him. And he is loyal to her, Also i beliebe its time for him to have some adventures off world NOT Being APART OF Legion VARUS. Maybe these new adventures would be a start of him creating his own Legion. A Private but A well paid legion, going places govt. Earth cant go without creating Galatic size problems for earth and other planetary issues. And not just Earth. Just a thought. Im just tired of seeing double cross after double cross. MC gets a girl but cant keep a girl.

BV n James McGill are a great combo!!

You'd think at book15 that the formula might get stale but not so. Another great plot and plenty of humor. . . . . the humor is getting better too.
Keep it up BVL.
(I think JM should go hot air ballooning with me)

McGilll!

What a character! 15 books and still funny. Great job by the writer to continually evolve James while still keeping his hilarious and effective personality.

Read all the books, you won’t be disappointed.

This one was ok in the sense that it didn't vary from the canon. Thus if you've come this far, here's more of the same. We do get a variant of a previous race, a new NPC and some interesting tech that's presented, like all of it, as unexplained.

There is an interesting development at the very end where a significant player does transform into something that may cause complications down the road. This follows the transformation of a minor player that brings on the only half philosophical narrative in the whole series. Since it's that time in the world, the minor element introduced involves racism. Sigh.

Some of the action is getting more than shopworn such as the protagonist bragging that he has almost no attention span, is huge to the point that if motivated, he could take on a dozen trained fighters. He's still circulating through the same catalog of females.

To sum up, in the end, we have here a few hundred pages that advance the story a half step. There is a minor cliffhanger at the last page that hints toward V16.

Not much to say... the same old, same old story.
I cannot even understand why I keep on reading the series... While being the same, it is still entertaining and while it is able to put a smile on my face then it is worth it.

This is not much of a review, but this book 15 on a series that could possibly be summarized into a trilogy. The story never advances much, and there is always a catastrophic mess that the hero sort of stumbles upon, is blamed for, and then somehow fixes.

McGill pissed me off

No spoilers, but there is a section of this book where it was finally time for McGill to act like a fucking grown up and it was still nothing but sarcasm and snark. Royally pissed me off. Feel like McGill's character would not act in such a way given the circumstance.

This was not the best Undying Mercenaries book. No completion to the raid on Green World. How did Dominus escape? Why the 2 new plots at the end around Etta and Governor Nox? Just didn't seem well plan for a conclusion.

POPKulturowy Kociołek:

Fabuła Legion Nieśmiertelnych tom 15 opiera się na pewnych sprawdzonych i nadal mocno angażujących czytelnika schematach serii. Legion Varus otrzymuje kolejną niebezpieczną misję, która zabiera go na tajemniczą planetę. Miejsce to z jednej strony wygląda jak „zielona idylla”, skrywa jednak wiele swoich zabójczych niebezpieczeństw. Jedną z nich są buntownicy, którzy założyli na planecie bazę, która ma być wykorzystywana do atakowania ludzi. Powstrzymać ma ich oczywiście James McGill i jego towarzysze. Tam, gdzie pojawia się bohater, tam też pojawiają się przeróżne nieprzewidziane kłopoty.

Autor umiejętnie buduje tu napięcie, przeplatając ze sobą wątki polityczne, militarne oraz osobiste losy bohaterów. Dynamiczne starcia kosmiczne przeplatają się z intrygami i zdradami, co sprawia, że czytelnik nie może oderwać się od lektury. Nie brakuje tu również odrobiny całkiem niezłego humoru i oczywiście łóżkowych podbojów Jamesa (te niestety nadal kłują w oczy).

Na plus tytułu należy również zaliczyć wyrazistą obsadę bohaterów drugoplanowych. W przeciwieństwie do poprzednich odsłon tym razem mają oni znacznie więcej okazji, aby zabłysnąć, chociaż McGill nadal jest bezkonkurencyjną „gwiazdą”....

B. V. Larson has created a series that allows for focus on a sub plot, and a chance for growth. This book feels like a must read for any Sci-Fi fan. If this book is the end that would be just too dang bad. I really enjoyed alot of the character growth, and plot thickening. I really hope this series goes to thirty books. 🙏 Brian if you read my review please write more. Alot of Sci-Fi can be so dark. We love the fight. We enjoyed the changes and the organic feel. Not everyone can fight every war, have so many relationships and be an author. Hemmingway...we all love to play with lions in our own ways, whether we are a James or Etta McGill, Graves or Carlos. Sir, it would be a crime to end this series. Please, if it too much hire ghost writers. Don't shotgun this lovely gem. I confess, I really enjoyed the ending, but common... there is so more. What about the Wurr? This could easily turn into a situation of Rome's or another empires expansion. The Clavers can be even more of a cancer. It only takes more territory. A Novela to expand the context would work. Anyways, I would reccomend this series for any Sci-Fi reader, beginner or expert.

The Undying Mercenaries series has turned into one of my favorite popcorn sci fi series that I've ever had the pleasure of reading. But just like anything that is good that lasts a long time eventually there is going to be a dud. While a dud might be a bit harsh to describe here, (I still enjoyed this book) compared to the rest of the series this was not Larson's top work.

At book 15 I'm not gonna get into to much detail here but we are in familiar territory as far as the stories go. Again McGill is a pleasure to follow around. And while his antics may not be what some would call morally superior, it is still impossibly hard to not enjoy McGill's character.

Where this book was really good was in its ending. While other books sometimes leave you with questions, this particular book left me curious about what's next more than many of the others. Which is a great way to leave this book since it left me wanting more despite the fact that this book didn't add up to the others.

Bring on Ice World, Larson! I'm ready.

Even for this series the writing has taken a dip... we have the usual formulae of;

James McTurd anxious to sell out his friends, allies and species for personal gain, a piece of tail or just boredom, Check!
the earth and its population balanced on the razor's edge, Check!
wars and crises from previous books conveniently on hold, Check!
McTurd trying to sleep with every female and loosely humanoid creature he lays eyes on, by seduction, coercion or alcohol, Check!
McTurd being a low functioning semi-upright primate until a moment when confronted by ultra intelligent higher alien species and suddenly he mentally outmaneuvers everyone with golly-gosh darn hyuk hyuk's and inserted logic that makes no sense, Check!
McTurd goes AWOL, insubordinate and/or commits treason, Check!
McTurd costs the legion more by damaging his own side more than the enemy does, Check!

I'm so tired of McTurd I am just going to pretend he was sent to one of the enemy planets and made into stew and permed at long, deserved last.

Getting Tired of McGill’s BS

For some reason, between the last novel Edge World and this novel, I’ve become completely tired of and intolerant of protagonist James McGill’s BS. His completely idiotic response to so many scenarios is to lie his ass off for no good reason. I just can’t stand it anymore. The only redeeming quality of these books is Mark Boyett’s incredible narration. He truly brings characters to life like a few other narrators.

Regardless, I just can’t suffer through another James McGill novel. While his flaws and BS were sort of charming for a while, after 15 novels I am just done. This idiot clearly doesn’t learn anything from his mistakes.

This will be my last Undying Mercenary novel.

I normally really enjoy this series; however, this one left me wondering just what was going on. Most of the previous books in the series have focused on one planet, and the associated campaign being fought by the legion(s). This one, however, just seemed all over the place. Whole sections of the plot just seemed to have fallen out, and what was there was terribly disjointed. There were also a number of continuity issues that were somewhat jarring.
Again, I normally really enjoy these books. Hopefully, this less-than-stellar entry in the series isn't a sign of things to come, as I would hate to see the whole series turn into a sloppy mess.

Looks like changes are happening again

Ya know most series I hope the MC doesn't have a kid, but with this series I kinda wished he had another one with any of the leader women in his life. He already had one with dust world princess. There could have been one with either the edge world princess or the blood world queen. There is also the allocator of rogue world, or the predator of earth, and the female of clone world. I can't recall any other good options, but I would mind another kid in the story.

McGill strikes again

James gets into and out of trouble several times throughout the book and even manages to find his way into some serious trouble and just as the axe is about to come down he squirms out of harms way. The legion ends up falling into a trap that has no path to victory. Even James can't find a solution. In the end they retreat and even more trouble is happening on earth. As always James finds a solution that keeps him from being permed and saves earth from being destroyed by the mogwa

Gotta like McGill

McGill just continues to be himself, getting into and out of predicaments far more than any person really should have the ability to do so
As other reviewers have mentioned, this book jump around a lot. Green world figures into the storyline a lot less than previous worlds have done so in their respective books and the rest of the book is a Mish mash of McGill interacting with good guys, bad guys and the Mogwa Governor. Will be interesting to see if future books refer to the deal he made with her

This one is slightly more interesting than those that came before it. But not by a lot so I added a star. otherwise pasting below:
Just going to paste my last review for Glass World here (I'll change it up next time if there is anything worth saying): I mean these books are mostly the same now, and so are my reviews of them. This one as about the same as the rest. I think I am settling into these things like a sitcom or cheesy syfy show that you can put on without too much to think about and unwind from work. There is value here in that way. So I guess I'll keep going.

Another excellent edition in the Undying Mercenaries series. And the next one due out in just 10 days (#16 - Ice World). In so very many ways all these books are the same. Notably as we follow "the McGill creature". But somehow there's twist enough in the overall plot and, well, just so much more to keep me interested with each successive book. Narration is quality of course. Mark Boyett really makes me feel the MC plus others as well. Looking forward to Ice World. Already have it pre-ordered.

Always good.

I drop everything else when a new B.V. Larson Undying Mercenaries book comes out. Doesn't matter what series I may be in the middle of, B.V. takes priority, and I'm never sorry for my choice. Read the entire UM series, maybe more than once, to meet some great characters and get some great action.

Very enjoyable series!

These are really fun and always exciting to see what shenanigans McGill is going to get into.

Character development is very solid as well as good plots and just an all around fun read. Really look forward to every installment and have reread the series twice now.

Would probably translate to animation fairly well! C'mon Netflix!

I'm amazed at the quality of the series so far

I've read all the books since the first one. Honestly, I thought at some point the others would run out of steam but that hasn't happened. A solid addition to the series.

In fact, if anything I found this one to be far more emotional than the previous ones.

Great, as always

The right blend of derring-do, humor, and general fun infuse this new, equally imaginative, and highly entertaining episode in the lives of James, Drusus, Graves, Galina, Winslade, the Claver clones, Carlos, Kivi, and many more quirky and eminently-lovable, -admirable, and/or hate-able people.

Thanks for another great one!

15 books and it’s still enjoyable

I love when I get a notification that there’s a new book in the series. Generally enjoyable and a fun, entertaining read.

My only comment would be is that I’d like to series start progressing more with the overall story—essentially move the needle towards how will this end?

A more mature McGill

Different but yet familiar vibe to this book.
I still enjoyed it but felt like this book missed a climax moment. Definitely a book leading up to the next book in the series. This is not a stand alone book and would be unenjoyable to someone not familiar the Undying Mercenary Universe.

good read

As usual McGill is in the thick of things! If commands needs a “volunteer” for missions that could result in being permed, what better way to get rid of their biggest pain in the butt! They can try! Read the book and hear how the best lier, storyteller and just plain luckiest excuse of a soldier fairs.
