Alternate cover edition of ASIN B06W5SDKYG

Now that the truth of the genetic experiments on Mars has been revealed, new missions are on their way to gain control of this extraordinary technology. In the process, they seek to exploit and enslave the colonists—turning them into nothing more than lab rats.

Worse, these newcomers are well armed, and prepared to go to war with each other to win control of the colony and its people.

But Dr. Jann Malbec has a secret, one that she could use to spare the colony and save the colonists from this fate. However, by using it she will almost certainly doom Earth to a planet-wide pandemic of apocalyptic proportions.

Yet she must choose. Earth or Mars—which is is going to be?

Well what can I say, another great chapter in the series and another very solid 4*/5 for me. My comments here don’t really change from the last couple of books. Still a good fun read, still plenty of action, still lots of excellent Mars-ing going on. A really fun space opera which I thoroughly recommend. And on that note I’m off now to read book number 4.

This completes the opening trilogy of the Colony Mars series as corporations converge on Colony One to force the secret of immortality out of Jann. Jann doesn’t believe she has the secret of immortality. She has the secret to a plague, but more on that later.

With years to prepare, the Colony was not ready for the arrival of the various corporations with their military hardware and insistence that the clones aren’t really human so they can do anything they want to them. This is a big problem that really didn’t have to be. For example, the colony can manufacture explosives, so why didn’t they mine the heck out of the area surrounding the colony? They could also have made primitive artillery which would have threatened the landing ships. In short, with a few basic precautions, nothing that happens in this book would have had to happen. There would still have been drama, it would just have been drama with an intelligent group of heroes. Instead, they resort to a biological weapon—the plague made by the corporation that started the Mars colonies in its efforts to find the secret of immortality. Let’s be clear, the woman who has worried nonstop about the ethics of the plague uses it as a biological weapon instead of manufacturing a few explosives that would also have won the day.

And of course the colonists lose control of the plague and it gets back to earth starting a sort of a lightweight zombie apocalypse. I also didn’t feel that the ultimate solution to the trilogy was particularly convincing, although it does set the stage for future books. In summary, it seems to me that these books lost steam as the trilogy advanced.

Did I hear it right? Luka Modrić has changed his line of work and now he's one of the prime movers and shakers on Mars? This author has strange penchant for Croatian names and words (Luka Modrić, Jezero city), or at least Croatian dictionary lying on his desk, which is as good source of seemingly made up words for a non-speaker as any, I guess.

This book, like the first two, is about Mars. If you are into being stranded on Mars, you will love it, if you are not…maybe not so much.

This is Book 3 in a series of 5. I'm rating it a 4, because it kept me reading, when the other incentives were not as great. It's a relatively simple plot, which I was able to predict reasonably well.

However, the character development was quite good, over the whole series. With each new book in the series, the characters get deeper. There are interesting and unusual twists in some of the character development.

There are two more books in the series. I'm not sure where it will go, because this book did a major resolution of the plot. But I'll probably read them, so stay tuned.

Colony Three Mars was back to a similar vibe as the first book. I think I’m drawn to the pandemic plot line lol! In this third installment we are still following Dr. Jann Malbec as she tries to save the colony — once again — and deal with relationships and where her home is. The Chinese and the COM teams throw a different mix into the equation. I do wish there was a little less abruptness as the story lines change and develop, as I sometimes feel we have skipped some info. I’m also not sure where the story is heading after this ending. That said, I still enjoyed the book.

The dialogue issue is back once again. Earthlings land and just sound insane and/or just flat as people. There are positive aspects to this book. Again there are really cool technical considerations that seem to have been well thought out. I also have a love/hate thing going over the b-movie type one-liners that pop up.

Loved the first book,
The second was ok but this was basically just a repeat of book 2 and it was really frustrating to read. The chapters that I really got into were the last few.

Oh my. Even though I’ve adapted to the constant action, this was the best of the series. Laughed out loud on the plane when Malbec discovers what kills the bacteria. I am now a fan of near earth science fiction. The role of governments vs billionaires in space is prescient.

A steep decline from tue first book.

*spoilers*
I was a little disappointed with the third book, mostly because it seemed like the author just glossed over a lot of the details of the last book to make the plot work. There was an explosion that killed all the hybrids except one, who became the 'leader' of the new council, um what? In the last book they're creepy, never speaking hive mind enforcers and now the only one left is this perfect person? Bizarre. Just the idea that all the hybrids are in one room at the same time is pretty unbelievable. Lazy writing.
The next part that makes no sense to me is how the colonists know for a fact earth will send people.. but repeatedly, it's said that they are 'powerless' against them. In the last book nills was able to create 2.5 rail guns in SIX hours, but in this book a mere six Chinese astronauts are able to hold everyone hostage...Uh, ok. The author has nearly everyone just 'hide' and act helpless, even though these people have already been subjugated and fought for their freedom once... But this time, they just decide to roll over and see what happens? Sure, they need supplies, but if they're so positive the battle will happen (they talk about it at the council meeting) then why on Earth didn't they create some sort of weapons, locks, or protections?
Basically, the battle is won by giving up and cutting a deal with the third group of astronauts to swoop in conveniently when the plot needs them. This book was written wuickly, as if the author wanted to be done with it.

Absolutely loved the first three books in these series. The fourth one ruined it for me. However, with that said, the first three books were so enjoyable that I'd recommend them anyway.

“I want you to have it, Freddy. It would make me happy, and my father, to know it was in good hands.” He just stood there speechless, for a few moments. “What about you? I mean this is your home.” Jann looked around again, slowly this time. “For a long time I thought of this place, this Earth, as my home. But now as I look around, all I see is what’s not there anymore, what’s gone.

I now understand that home is not about place, it’s about people. Coming here finally made me realize—my home is Mars.”


You’re too nice. Nills. You believe that humans are genuinely good. But in my experience, everybody wants something, and it's generally not your well being. He found it hard to be that cynical, even if there was a grain of truth in it.
...
“There it is, Colony One.” “Ahh, the fabled El Dorado of the solar system.” “What was that?” “It’s what some people on Earth call it, El Dorado. The legendary cursed city of gold.”
...
She thought of home, of her father’s farm. How she longed to walk the hills again, in the fresh clean air, with no need for EVA suits and life support. All the things the Earthlings took for granted. They didn’t know how good they had it, always wanting to go one step beyond. How she would love to swim in a lake again, like when she was a kid. Those were happier times. How she missed them, the simple things: air, water, grass—and family. All gone now...
...
Finally, Dr. Foster spoke. “You’re playing a very dangerous game. Billions of lives are at stake here, you seem to forget that.” Jann leaned in to the table. “Did we create this monster that is raging across the planet? No, Earth did. Did we start this war of worlds? No, Earth did. Did we seek to enslave the people of Earth? No, but they want to do that to us. You’re right, Dr. Foster, this is a dangerous game. If you want to start a war, then you best be prepared for the consequences if you lose. We didn’t start this, but we’re sure as hell going to finish it.”
...
On the side of the small craft was emblazoned the newly designed Mars flag. It was not unlike the Japanese flag, a red disk on a white background. However, this had two smaller disks, one on either side of the main one. These represented Phobos and Deimos.
...
It would be like it had always existed. It seemed to work, as the emblem now popped up everywhere. A number of colonists had already scratched the flag out on the surface of the crater. Large enough to be seen by hi-res satellite. Images of the colony were now flooding back to Earth to feed the insatiable interest in Mars, which had now reached fever pitch since the UN resolution.
...
Those on Earth that were infected and had survived would now have the same physical benefits that Jann and the colonists on Mars had, fast healing, longevity. They would presumably be the new elite. The bacteria had been eradicated but she had no doubt that samples had been saved and stored in labs all across the planet. How humanity would deal with the consequences of this event would be for historians to report.
...
Speculation abounded as to how this event could alter the course of human evolution. Was this the point were the genus of Homo sapiens forked and diverged, with a kind of new super race branching off from its root? Who could say? But there was no question that things would ever be the same again. It was estimated that, at its peak, over fourteen million people had been infected. A significant number, but still less than 0.2 percent of the global population. Of that number, a significant portion had been radically altered biologically, upward of four million, and another six million to a lesser degree. The big question now was, could this superhuman trait be passed on, could it be inherited?
...

Gerald M. Kilby delivers a gripping continuation that kept me on the edge of my seat throughout. This isn't just science fiction - it's a thought-provoking exploration of what could realistically go wrong when human ambition meets the harsh realities of Mars colonization.
What really struck me was how Kilby exposes the dangers of letting financial interests drive such critical decisions without considering the human cost. The book paints a sobering picture of how corporate greed and heartless profit motives could turn humanity's greatest achievement into its most catastrophic failure.
The scenarios Kilby presents aren't far-fetched fantasy - they're uncomfortably plausible future realities that got me thinking long after I finished reading. As someone who appreciates strategic planning and risk assessment, I found myself considering how these monumental steps toward Mars colonization would need to be executed to ensure success rather than disaster.
Kilby doesn't just entertain; he challenges readers to think critically about the intersection of commerce, technology, and human survival. The book serves as both an exciting adventure and a cautionary tale about the importance of putting humanity first when venturing into the unknown.
A well-written, quick read that asks some deep questions about our future among the stars. Certainly got me thinking about what it truly takes to succeed when the stakes are literally life and death.

aren't words better? Stars say nothing about the book

I listened to this as a full set. It starts with a team going to Mars to figure out what happened. As group of colonists suddenly went silent. (It was being broadcast like reality tv) But of course, this doesn't go smoothly and chaos blooms. Contact is made with the colonists and their crazy scientist ruler.

Then we had the adventures of over throwing the crazy scientist ruler and figuring out what to do with the leagues of clones that he made.

And the third joined the Martians as they are now subjected to the arrival of Earthlings. You heard that right. Greedy people on Earth have taken to the vacuum of space to establish their right to ownership of Mars. What will the locals do?

I think this was a reasonably possible turn of events. No, not like it's going to happen now. But what happens when a rich corporation wants the elixir of youth and they have a mad scientist willing to give it a shot? Yeah, a place is created and they use whatever components (people) are available. There are no rules on Mars, no laws, and no oversite just in case someone wants to charge them with immorality. I liked the characters. I liked the story line. I hope they do have a happy ending.

Book three keeps the story moving with echoes of real life events

The story for Jann moves on with the arrival of the Corporations trying to monetise the bacteria created on Mars. This naturally results in Jann going back to Earth and gets the full celebrity treatment - "She had swapped one enclosed, encapsulated environment, that of Mars, for another, that of celebrity. And like Mars, moving outside the protection of the bubble could be perilous."

And guess what, greed gets in the way of doing the right thing. Who'd have thought that...

SPOILER ALERT It gets better with a throwback to COVID.

"What is happening on Earth, right now, is an unfortunate by- product. It is a self- inflicted wound, not of our making. Yet, by an ironic twist of fate it seems that the tables have turned and it is we who have the power of life and death on those who seek to enslave this place, these people— my people.”"

Finally she makes a decision on where her future lies "Jann looked around again, slowly this time. “For a long time I thought of this place, this Earth, as my home. But now as I look around, all I see is what’s not there anymore, what’s gone. I now understand that home is not about place, it’s about people. Coming here finally made me realize— my home is Mars.”"

The romp continues

Steve Cole using wife Leanna's account: as a space romp it is highly readable and fun. Science went out the window with the clones of book two and the fountain of youth bacteria of book one. Never mind that humans couldn't get Biosphere to work or that no one has a clue if humans can live for months or years in 38% gravity.

This one is all politics that would make sense to Hollywood. Maybe the final treaty would work in the real world. The Chinese arrive to take over the fountain of youth bacteria, declaring that they do not accept the court ruling that gave Mars back to the corporation two weeks behind them. War erupts with plasma guns and other weapons. After the war ends and both China and the corporation return to Earth with the bacteria, Jeff Bezos of SpaceX --- EXCUSE ME --- Lane Bezos of AsterX arrives to rent space for a way station to his planned asteroid belt mining plan.

Just keep telling yourself ... IT'S A ROMP, just go with it.

Book three of Mars Colony continues to be exactly what I signed up for: fast, scrappy, and fun. It reminds me of those old low-budget sci-fi channel shows - cheap sets, questionable science, and characters you can’t help but root for. And I mean that in the best possible way.

At this point, the cast feels like old friends. I’ve especially grown attached to Gizmo, the adorable little robot who has no business being this endearing. At this point I am more invested in his fate than in whether the colony survives.

The pacing? It doesn’t meander. You’re dropped into the action, it zips along, and before you know it, you’ve burned through another book. Does it sometimes sacrifice depth for speed? Uh, yeah. But I wouldn’t want in any other way.

Am I in for book four? Absolutely. I want to see how much more trouble this crew - and Gizmo - can find before Mars finally decides it’s had enough of them.

This third book of the series was as original and fresh as the first, with the exception of the use of the phrase, "the quirky robot," used to describe Gizmo, one of the most enjoyable characters. Mars settlements become a political hot potato between the Chinese and certain other political powers, and military force is sent to manage a peaceful turnover of facilities. This, of course, does not happen, and Jann Malbec is challenged to find a way to end conflict and save Mars, and safeguard the secret of the longevity virus. The story is put together seamlessly and the characters act in character: that means that their character and decisions move the story to where it must go. Jann must and does make the morally right, but politically and practically difficult decisions. A very good installment in this thought-provoking series.

Ha ha, sm preslišov uvod in poslušov kr tretji del namesto drugi :)

Pa me ni veliko zmotlo, edin se mi je zdel da je kar velik preskok od tega da je ona sama ostala gor in zdj kr neki kloni živijo z njo, Marsu pa se bližajo tri odprave z Zemlje. Kitajci, COM ljudje in ena rudarska manjša ladja... Vsi od teh bi si radi prilastil Mars zase in so se pripravljeni spopadat med sabo, te ljudje, ki so pa že gor, so pa potisnjeni vmes...

Dr, Jann, znanstvenica iz prve knjige, se odloči in spet spusti bakterijo na prosto, da okuži tako kitajce in CoM ljudi in se poskušajo pote v zmešnjavi rešit. Sami so imuni že na bakterijo. Kitajci hočjo pobegnit nazaj na Zemljo, Robotka Gizmo in kitajski se stepeta med sabo in je kitajski "razstreli" pa še Gizmota s sabo potegne :(

Baterija pride na Zemljo in okuži svet, počasi se začne širit in nikakor je ne uspejo ustavit. Dr. Jann prisili UN da prizna Mrrs kot samostojno neodvisno ozemlje in v zameno jim da zdravilo - kanabis, Niels je skoz kadil in se tako ni okužu, ha :) Edini pogoj k ji dajo je da more prit na zemljo osebno prevzet da bo dogovor veljaven...

Zlo fajn!!

The genetic experiments on Mars have been revealed to Earth which prompts a response in the form of new missions to the red planet. The missions from Earth are from private and state-sponsored powers that are prepared to do whatever it takes to wrest control and ownership of the martian colony from the colonists. Their intent to understand and secure the knowledge of the genetic anomalies of the martian colonists will be realized at any cost. Those costs could mean starting a war on the martian surface or the subjugation of the colonists as lab-rats, or both.

Kilby's writing prowess is evident as he continues to carry the reader along on this ever-evolving adventure. The book is hard to put down.

3.5 stars, but I'm feeling generous.

As with the previous two books in this series, it is largely plot-driven with not much in the way of character development. The characters, especially the colonists, were uniform and the only way of telling them apart was their names as no-one was adequately described and they had no distinguishing features.

Having said that, the plot is quite good and comes to a satisfactory ending with many loose ends tied up.

As for the writing, it lacks sophistication and commas are overused. Dialogue, however, is quite realistic.
