With 16 literary awards, from the #1 bestselling series, Tachyon Tunnel 4 delivers a masterful blend of epic space adventure rooted in real, yet understandable science, and powerful human connection. Written by futurist and innovator Michael Gorton, founder of Teladoc and a pioneer in multiple industries, the Tachyon Tunnel series reflects a rare combination of storytelling, visionary thinking and authentic scientific insight.
Humanity has crossed the threshold of impossible. With tachyon tunnel technology now unlocking instantaneous travel across space and time, Alex Durant and his allies have pushed civilization to the brink of a Kardashev Type II future, harnessing the energy of stars, reshaping planets, and rewriting the limits of physics itself. But as power expands, so do the consequences.
In the aftermath of devastating conflict with the Daklin Empire, a deeper truth begins to surface, one hidden not just across galaxies, but across millions of years of carefully orchestrated history.
At the center of that truth lies Eidolon, a Type II+ civilization established in the remote Large Magellanic Cloud. Eidolon was established at the beginning of the Daklin reign by a race intent on preserving civilization from the destructive influence of the Empire. It is a civilization far beyond the Daklin technological horizon, bound by ancient rules designed to prevent its own destruction. Eidolon holds secrets so profound it could either secure humanity’s future… or end it.
As Alex and his team are drawn into Eidolon’s inner workings, they uncover a system built on extraordinary achievement, and dangerous restraint. While humanity races forward, eager to expand, explore, and defend itself, Eidolon has chosen a different path: isolation, control, and the suppression of forces it deems too risky to unleash.
Caught between competing visions of the future, one of limitless expansion, the other of enforced equilibrium, Alex must confront a question far more significant than any enemy fleet: Should humanity become everything it is capable of… even if it risks transforming into the very thing it fears?
As new alliances form, hidden histories unravel, and technologies emerge that challenge the nature of reality itself, the line between salvation and catastrophe begins to blur, because in a universe where time is no longer a constraint… the greatest threat may not be what comes next, but what has already been set in motion.
About the author Michael Gorton has written books that entertain, educate, and inspire. The Tachyon Tunnel series combines time travel, romance, adventure, and great mysteries of science into a novel that takes fiction to an all-new level!
Michael grew up as an Air Force brat in a lower middle-class family. Because of great influence from his parents and four siblings, Michael reached for the stars. With virtually no money in his pocket, he went off to college and earned degrees in Physics, Engineering and Law - all while working full time. After working 11 years as an engineer in corporate America, he is now a serial entrepreneur who has founded 16 companies. Amongst those are notables: Internet Global, Palo Duro Records and TelaDoc, now the world’s largest telemedicine company. Michael has been a prolific writer, authoring technical articles on a wide range of topics including Internet, power systems, remote metering and disconnect, solar, electric vehicles, healthcare, telemedicine, astronomy, physics and music.
Broken Handoff was Michael's first business book. It was the amalgamation of three decades as an entrepreneur developing companies. The two authors bring a wealth of new perspectives that addresses one of the biggest problems in funding and M&A events. Broken Handoff was named the #1 M&A book in 2019 by Book Authority and has been in the Top 10 on Amazon's chart.
Forefathers & Founding Fathers was Michael’s 5th novel, earned several awards, and reached the #1 slot in Historic Fiction on Amazon's chart. The first four: USSA, Lex Talionis, Tachyon Tunnel, and Born Again American were all written for fun with the intent of giving copies to a small group of friends and family. That was in fact the goal with Forefathers, but while researching the topic, Gorton realized this was an important and unknown story that needed to be heard. Forefathers has received positive reviews from some of the world's best-known authors, including best-selling author Mark Victor Hansen (Chicken Soup for the Soul) and Jim Stovall (The Ultimate Gift).
Michael is a runner, martial artist and mountain climber. He and his family are currently climbing the highest points of elevation in the fifty states. They have 42 done.
Michael is an 11th generation descendant of Samuel Gorton. His lineage is: Samuel, Samuel, Samuel, Benjamin, Amos, Oliver, Guy, Dayton, DeForest, Everett (dad).
Michael Gorton’s Tachyon Tunnel 4 is a blend of hard science fiction with an emotional and philosophical narrative. Readers follow Alex Durant and his team as humanity goes beyond space and encounters new civilizations, technologies, and a reality beyond their comprehension. It starts out as an ambitious scientific mission and becomes something much bigger. The crew travels to worlds like Oiket and Eidolon, and questions surrounding human evolution, AI, identity, love, war, and survival cannot be avoided. Meanwhile, Alex, a brilliant scientist, is trying to navigate these discoveries that could permanently reshape civilization.
I was very impressed with what Michael Gorton did with this story. He balanced massive scientific ideas with humanity. Even with the hard science fiction, it does not feel emotionally empty, to my surprise. The emotional moments between the characters were some of the strongest scenes, besides the technological revelations. When Shelby made the decision to stay behind on Oiket, that was an emotional turning point for the narrative. But it also made Alex realize that everyone is not meant to walk the same path, regardless of the love that exists between them. But the scenes aboard Tranquility between Alex and Megan were some of my favorites. They made the story feel warm and realistic with the discoveries of advanced civilizations and galaxy-altering reveals. I liked their conversations about things as simple as beer, loss, resilience, and purpose. Those are very human moments I look forward to reading about while the story explores concepts like stellar energy transfer, quantum engineering, and post-human societies. I also appreciated Megan’s backstory and finding out that her sarcasm and tough exterior were survival mechanisms she adapted after going through grief and trauma.
Another strength of the novel is the worldbuilding. Of course, you can not have a great science fiction novel without creating an impressive world and atmosphere. Eidolon, for example, felt ancient but also futuristic. The way it was described with its marble-inspired architecture, hiding technology that is capable of manipulating energy on a grand and unimaginable scale. The way Gorton explains things like resonance fields and civilization-level engineering was fascinating and didn’t feel overwhelming. I think readers will be able to appreciate this as well. At the same time, you can sense something unsettling underneath Eidolon’s perfection. There are repeated references to the mysterious “Second Council,” and Megan’s discovery of suspicious gaps in historical records creates the sense that something is being hidden. Gorton pulled this off perfectly. So, there is an added layer of intrigue beneath all of the scientific wonder.
The pacing works in the story’s favor because it’s not action-heavy, but more exploratory. Gorton doesn’t rush from one scene. There is that constant question, just probing as we’re reading: what happens to humanity when they gain access to technologies and civilizations that are beyond their comprehension and emotional maturity? The premise surrounding humanity confronting something so large on an evolutionary scale reminds me of Arthur C. Clarke’s Childhood’s End. But there were also some elements of interpersonal relationships and connections between politics and advanced science that reminded me of The Expanse by James S.A. Corey. Readers familiar with these books will certainly appreciate Tachyon Tunnel 4.
Overall, Tachyon Tunnel 4 has exceeded my expectations in the science fiction genre. I was fully invested from beginning to end, not only in the mysteries surrounding Eidolon and the Daklin conflict, but also in the emotional futures of the characters. Readers will love reading about the interstellar civilizations and seemingly impossible technologies, in addition to the human connections.
Tachyon Tunnel 4 is a science fiction adventure that picks up after a devastating loss and turns its attention toward survival, rebuilding, and the next stage of humanity’s fight against the Daklin. Alex Durant, Shelby, Megan, Emily, Zander, and the surviving Pronimos refugees retreat to Mars, where grief quickly becomes engineering, strategy, terraforming, and preparation for a larger galactic conflict. The book blends space opera stakes with hard science fiction ideas, especially around faster-than-light travel, Mars, planetary restoration, and the Kardashev scale.
I liked how this fourth entry in the Tachyon Tunnel series feels bigger but also more wounded. The opening is brutal. It doesn't let the reader glide past the destruction of Pronimos as just another plot event. There's grief here, and the book keeps returning to the question of what people do after their world has been burned away. Gorton’s instinct is always forward motion. Loss becomes a city plan. Trauma becomes a defense grid. Mars becomes New Pronimos. I found that both moving and very true to the series. These books have always been fascinated by the idea that smart people, given enough nerve and imagination, can punch through impossible walls.
I enjoyed the scenes where characters talk about terraforming Mars over food and drinks. One minute you're thinking about magnetospheres, oxygen levels, tachyon tunnels, and galactic empires. The next, someone wants Mexican food. It works because the characters have history together. Their jokes, grief, irritation, and loyalty carry some of the heavier science. The author also makes a clear choice to lean into explanation. This is idea-driven, optimistic, high-concept science fiction with a big heart and a tool belt.
Gorton isn't just asking whether humanity can survive an enemy. He's asking whether we can think large enough to deserve survival. That is where the genre work really lands. The faster-than-light travel, Mars terraforming, ancient civilizations, and Kardashev-scale thinking aren't just shiny science fiction furniture. They're tied to a moral argument about imagination. The book basically says that the future belongs to people who refuse to stay trapped in small thinking.
I would recommend Tachyon Tunnel 4 most to readers who already like the series, especially those who enjoy science fiction with space opera momentum, big engineering solutions, ancient-civilization mysteries, and characters who solve problems by building something audacious. For returning readers, it's a strong continuation.
I received a free copy of this book, but my review is my honest opinion. I actually went into Tachyon Tunnel 4 without having read the previous books in the series, which normally would make me hesitant with science fiction because of how much world-building and background information these stories usually contain. Surprisingly though, I still found myself able to follow along well enough to stay invested in both the story and the larger concepts being explored. What stood out most to me was the scale of the ideas in this book. There’s a lot involving advanced science, space, time, technology, and humanity’s future, but it never felt like the book was trying too hard to sound complicated just for the sake of it. The scientific concepts were clearly a major focus, yet the writing stayed accessible enough that I never felt completely lost. I also appreciated the pacing because the story consistently felt like it was moving forward. Every time I thought I understood the direction things were heading, another layer or complication would get introduced that expanded the scope even further. It gave the story a very cinematic feel at times. Even though I didn’t have the emotional attachment that longtime readers of the series probably have with the characters, I still found the overall tension and larger stakes interesting enough to keep reading. The book does a good job balancing action, scientific ideas, and human emotion without leaning too heavily into only one aspect. Overall, I think fans of thoughtful science fiction — especially readers who enjoy stories involving advanced physics, futuristic technology, and large-scale existential questions — would probably enjoy this series quite a bit. Even jumping in at Book 4, I still found it engaging and interesting enough to make me curious about the earlier installments.
I ended up enjoying Tachyon Tunnel 4 quite a bit. It's one of those books that throws you right into the deep end and never really lets up. The stakes feel massive from the very beginning, and the author does a good job making the destruction of Pronimos feel like an actual tragedy instead of just another sci-fi planet blowing up for shock value.
What I liked most was the sense of scale. Entire worlds are at stake, civilizations are hanging by a thread, and you can feel the weight of that throughout the story. Alex continues to be my favorite character because he's not just some action hero. He's angry, grieving, and wants revenge, but he still manages to think strategically when it matters most. Emily and Megan also had some great moments throughout the book, and their interactions helped balance out some of the heavier parts of the story.
One thing that really grabbed my attention was the mystery surrounding Pronimos and the strange sensor readings. It starts off as a small detail that could easily be overlooked, but it becomes one of the more interesting threads running through the story.
My biggest complaint is probably the pacing. The book moves fast. Sometimes that's a good thing because it's hard to get bored, but there were a few moments where I wished the story would slow down and let the emotional scenes breathe a little more. There were also a few sections where the science and technical explanations got a little dense for me.
That being said, if you're already invested in this series, I think you'll have a good time with this one. It has plenty of action, some interesting sci-fi concepts, and enough mystery to keep you wanting to see what happens next. It may not be my favorite book in the series, but it's definitely a solid entry.
I also would like to add that I received an ARC of this book.
This Series Just Keeps Getting Better I don't usually read a lot of sci-fi, but this series pulled me in and Tachyon Tunnel 4 did not disappoint. From the very first chapter, I was hooked. The book opens with the destruction of an entire planet Pronimos and the emotional weight of that hit immediately. Watching Shelby fall to the floor searching evacuation logs for her children while Alex is trying to hold everything together? That's not just action, that's real storytelling. What I love about Michael Gorton's writing is that he balances the big epic stuff space battles, tachyon tunnels, planetary colonization with real human moments. Alex is brilliant but he's also grieving, conflicted, and trying to lead people through the impossible. That makes him feel like a real person, not just a hero. The Mars settlement storyline was one of my favorite parts. I loved how the author thought through every detail the rings, the spokes, the hydroponic farms, the magnetic field problem. It felt believable, like something that could actually happen. And the little scene at the Mexican restaurant in Dallas while they're planning a city on Mars? That was such a fun contrast totally unexpected and it worked. Emily's evolution from AI to something more human, Megan's bold energy, Zander stepping more into his own all of the characters are growing and I'm invested in all of them. And that ending?! Maria reaching out through the plink saying "Alex... help me" when she's supposed to be dead?! I need the next book immediately. If you like space adventure that actually makes you think AND makes you feel, pick this up. Just make sure you read the earlier books first so you know what's going on you won't want to miss any of it.
Tachyon Tunnel 4 is an ambitious and emotionally charged continuation of the series that expands its universe while grounding the story in grief, survival, and humanity’s future. After the devastating destruction of Pronimos, Alex Durant, Shelby, Megan, Emily, Zander, and the remaining refugees retreat to Mars, where mourning quickly transforms into action. Mars becomes more than a refuge — it becomes New Pronimos, a symbol of resilience, rebuilding, and preparation for the growing conflict with the Daklin.
What makes the novel stand out is how it balances massive science-fiction ideas with deeply human moments. Gorton blends faster-than-light tachyon tunnel technology, terraforming, ancient civilizations, and Kardashev-scale concepts into a story that still finds room for conversations over food, humor between friends, and the emotional weight of loss. The science never feels like decoration; it supports the book’s larger themes about imagination, ambition, and whether humanity can evolve enough to survive its own future.
The novel also introduces darker questions about unchecked progress and the consequences of technological evolution. Gorton constantly blurs the line between salvation and destruction, suggesting that humanity’s greatest threat may already be unfolding. Packed with revelations, large-scale engineering solutions, and major plot twists, the book feels both intellectually ambitious and emotionally grounded.
For readers who enjoy idea-driven science fiction, space opera momentum, and stories about solving impossible problems through audacious thinking, Tachyon Tunnel 4 is a powerful and thought-provoking entry in the series.
Tachyon Tunnel 4 is a massive, sprawling science fiction novel that deals with survival, with grief, with discovery and with what kind of future humanity deserves. The book opens after the destruction of the Proninos and the surviving characters are trying to come to terms with what has happened. But then there is Mars, a vast and wonderful place and the novel quickly grows to fill the space of the red planet and becomes the second home of the characters who are searching for a new beginning.
There is so much going on in this book. There is the terraforming of Mars, the tachyon tunnels, old civilizations, time and space manipulation, war, family, love, loss and so much more. The book focuses a great deal on the technology in the story and the scope of it all. The author put a great deal of thought into creating believable science and a believable world. Some of the parts that the author used to explore the world were so cool. Others were just kind of slow because the author spent so much time explaining the details of the science or the world and not enough time to really evolve the emotional part of the story.
On the other hand, the book has done a great job with the human side characters in this story. It was really cool to read the interactions between the main characters and the side characters in this story as they travel through space and time to get back to their home. The story really has a lot of heart and it was great to read as the characters struggled to come to terms with their loss and move on from it. Reading their growth as they deal with their personal problems and fall in love was really great to read as well.
Tachyon Tunnel 4 by Michael Gorton is just wow. This book is mind bending stuff. Gorton has taken the concept of tachyon tunnel tech, instant travel across space and time, and cranked it up to eleven, leading to some unbelievable advancements. It’s the kind of science fiction that makes you sit back and seriously question what’s even possible. What really stood out to me, beyond the flashy tech and potential for epic space battles, is how Gorton adds this whole other dimension to the story. It’s like pulling back a hidden curtain on a history that’s been built over thousands of years. It gives the whole story so much more depth. He doesn't pull any punches when it comes to the potential dark side of unchecked ambition. The main character has to deal with some pretty heavy stuff about what it really means to evolve. Without spoiling too much, this book is absolutely loaded with revelations. Gorton does a fantastic job of blurring the lines between what could save humanity and what might actually be its downfall. The idea that the biggest threat might not be something lurking in the future, but something that’s already in motion? That’s a powerful concept, and it just casts this amazing shadow over the entire story. Overall, Tachyon Tunnel 4 is incredibly ambitious. Gorton manages to expand this universe in awesome ways while somehow keeping me hooked on the core drama. If you're into sci fi that makes you think and throws in some massive plot twists, you absolutely need to pick this one up.
An amazing continuation of the Tachyon series. A group of survivors led by Alex who have to bring a dead planet, Mars, back to life, a planet which has been dead for over 66 million years. Forced to start over again by the Daklin, a force which can obliterate planets. They have just begun to bring the planet to the point where they can survive and prosper when somehow the Daklin find them. And only because of Alex's genius are they able to save themselves by using the tunnelling method to send the Daklin ships directly into the sun to be incinerated. I have to say BRAVO to that. But unfortunately their way of life is not for everyone and Alex's wife decides to leave to return to the ranch at Oiket and Alex is off to other galaxies that have survived in order to try to understand how they did so. A fast paced, character driven novel and the characters are so well depicted that you completely identify with them. And Megan finds a hidden space compound that only she was destined to find, one that led them onto their next adventures particularly after meeting Lysandros, who had been gone for millions of years, but who had planned ahead for mankind. Now it is time for Eldolon a Type II civilization that has achieved mastery over the total energy output of its star and whose inhabitants can live for thousands of years. What a journey that turns out to be. I would highly recommend this series as you get rapidly caught up in it and the energy doesn't stop. An excellent novel and one that will that you will probably want to re-read along with the precursors.
Tachyon Tunnel 4 by Michael Gorton is a fantastic addition to the series and one of the most intriguing sci-fi novels I've come across in a while. What starts as the fallout from a war with the Daklin Empire quickly expands into a profound dive into civilization, power, the importance of technological limits, and where humanity is headed.
The introduction of Eidolon was incredibly intriguing. This Type II+ civilization, tucked away in the Large Magellanic Cloud and adhering to old rules to prevent its own destruction, brings a remarkable sense of scale and mystery. I appreciated how Gorton intertwined vast scientific ideas with real philosophical dilemmas about whether pursuing endless progress is worth the associated risks.
Alex and his crew continue to be engaging characters, especially as they grapple with the push and pull between humanity’s aspirations and Eidolon’s cautious approach to isolation. The revelations about hidden histories, cutting-edge technologies, and the nature of reality continually raised the stakes in unexpected ways. The notion that the biggest threat might already be in motion adds an unsettling layer to the story.
This book encapsulates all the elements that make great science fiction: a grand scale, smart world-building, emotional depth, and thought-provoking concepts that linger in your mind long after you turn the last page. Tachyon Tunnel 4 is a remarkable and immersive experience that no sci-fi fan should overlook.
Tachyon Tunnel 4 continues Michael Gorton's ambitious space opera with the same enthusiasm, that made the earlier books fun to read, and raises the stakes considerably. Planet-scale terraforming, time displacement, galactic warfare, and a father-son relationship at the emotional core all make for an entertaining and heartfelt read.
The characters continue to be what drives the series. When Gorton lets his characters just be in the world he's built, the book is at its best.
My main point of criticism with the book is the science delivery. Some of the technical explanations work through calculations in real time, which can slow the narrative momentum just as things are becoming exciting. Readers who love hard sci-fi will appreciate this, but those who prefer the drama at the forefront could find themselves skimming a few passages.
The ending has me curious about where Gorton is taking things next. If you've been along for the ride since book one, this is a great continuation. And if you're new to the series, I highly recommend starting at the beginning.
Michael Gorton has written another fantastic book with Tachyon Tunnel 4. I thought the third one was my favorite, but they honestly keep getting better and more intense.
The book begins with an incredibly heartbreaking scene where the Daklin Empire destroys the planet Pronimos. Watching Shelby desperately search the evacuation records right as the network goes dark is a moment that you will sit and think about. It actually almost made me cry.
Not only are there huge things at stake and a HUGE main plot, but the plot keeps you on your toes with smaller, thrilling side stories. For instance, Megan discovers an ancient alien site hidden under Olympus Mons and has to survive a dangerous encounter with a killer named Blunt. That. Was. Crazy. Later, when the team travels to new planets, Shelby’s choice to stay behind on the world of Oiket was unexpected. I literally gasped.
I can’t wait to read the next book and see what happens to the characters. If you love crazy sci-fi with a constant thrill of, “what ELSE can happen?!”, please read this series. Start at the first book!

Advanced copy reviews. I went into Tachyon Tunnel 4 without having read the other books in the series. While k had some catching up to do, I was able to pick up and enjoy the book all the same. The world building for this story is great and makes me want to go back to pick up the other three books. I fully believed we experienced a major and catastrophic loss. I fully believed we were working tirelessly to start a new colony in an uninhabitable planet. I loved how our main characters went from “tech talk” where they’re explaining the science behind things, to getting excited about transporting to a Mexican restaurant for lunch. The characters were well developed in terms of experiencing real emotions in a crisis time. For non science fiction fans and fans alike, I felt this was a well written, thought out read. The writer makes it easy to follow along but also goes in depth into the science behind the endeavors as the team seeks to essentially build life on Mars.
This was a very interesting book. I hadn’t read the previous books in the series, so I wasn’t sure what exactly had happened at the start. There was a lot of science and this book seemed to have harder science than your typical science fiction book. The reason why I rated it a bit low is that I thought the main character, Alex, was a bit of a Mary Sue. There are two separate scenes where he’s convened a group of science in order to solve a problem with the Mars colony. In both cases, the scientists come up with a solution that will take an infeasibly long time. Then, Alex says, of all things, “you’re thinking like scientists,” and comes up with a reasonable solution either on his own or with the help of his son. At that point, why bother with the scientists? Why not just have Alex solve it in his own? It rubbed me the wrong way and I didn’t like it. Other than that, it was a pretty good book.
OK Besties... If you thought the stakes couldn’t get any bigger after Book 3… weeeellll, Michael Gorton said “hold my spaceship.” 🤭 "Tachyon Tunnel 4" pulled me right back into the chaos with intense suspense, massive sci-fi concepts, and twists that kept me flipping pages way past bedtime.
And listen… I am still not claiming to be a sci-fi girl, buuuuut this series keeps dragging me deeper into the genre in the best way. 🤭 Michael Gorton has this way of making all the advanced science feel exciting instead of overwhelming, while still keeping the emotional weight and danger front and center.
The scale of this story felt HUGE, but the tension? Even bigger. Besties, this series continues to deliver.💯
Tachyon Tunnel 4 by Michael Gorton is a highly satisfying, idea-driven hard sci-fi novel that masterfully balances massive space-opera stakes with genuine human heart. Reeling from the devastating loss of Pronimos, Alex Durant and the surviving refugees retreat to Mars, channeling their collective grief into an audacious plan to terraform the planet and build a massive planetary defense grid. The narrative scope expands beautifully as humanity seeks an alliance with a hidden, advanced civilization in the Large Magellanic Cloud to stop the predatory Daklin Empire. While the heavy technical exposition and deep dives into physics might feel a bit dense for casual readers, existing fans of the series will love how Gorton uses brilliant engineering and unyielding human optimism to solve seemingly impossible cosmic problems.
I truly enjoy a good science fiction read, and this series does not disappoint! The fourth installment continues with the treachery that the human race has had to face and the big decisions that need to be made to help ensure it's survival. The science used is most definitely based in truth, which lends itself greatly when the fiction portion starts to creep in and start to take over. It'll feels so real, and really makes you think about what would happen if these events really did come to pass. For fans of this series, you are going to be very pleased with how this story picks right back up where it left off and throws you deep in the middle of yet another treacherous obstacle for the human race. Will things ever be as they once were?? For newcomers to this journey, do yourself a favor, go pick up volume one and start this journey as we did, you definitely won't regret it!!
I was fortunate enough to read this as an ARC and share my honest opinion.
I was really hesitant when I was asked to read this book. I hadn't read the three others in the series, and I thought I would be totally lost in space. If this is your first book in the series you read, I can promise you that you won't feel lost. Gorton does a great job with his world-building and history; I felt like I had always been part of the action. Like any good science fiction, Gorton does a great job of telling a totally fictional story that makes me question things in today's day and age. It's a fantastical setting that has believable characters dealing with relevant problems.
I was pleasantly surprised by how much I enjoyed reading this book.
Good sci-fi. The science is interesting and plausible, which makes for good science fiction. I really only have 2 issues with the book. The characters need time to breathe and grow. Character growth happens but just kind of.... suddenly, instead of gradual. Also, it's kind of a cheat to use sex scenes to explain character growth. My second issue is the pacing. The book starts with continuous action, but when it slows down..... it doesn't show down. We don't get to see the characters grow, change, learn, and adapt. They just suddenly have adapted because it's 4 months later. While there's something to be said for skipping the boring parts, it feels like a missed opportunity for character investment.
This is book 4 in the series, but it was my first book and I found it inspiring as a stand alone. Science has built tachyon tunnels to make space travel through the universe in seconds or as escape routes from enemies of the human race. The story opens with the Dalkin Empire destroying Pronimos as Emily looses her entire family and Akex jumps into action to save the last of the world's 20,000 people. He has a plant turn Mars into a new Prominos. Mars has already been attacked by the Dalkins and they have destroyed its magnetic fields. Michael Gordon brings on the the science with realistic escape plans, rebuild plans and plans for a futuristic self sustaining society. Of course there are battles, near escapes, hardships and romance to round out this best seller.
Tachyon Tunnel 4 expands the series in an ambitious direction, combining big science-fiction concepts with emotional consequences. The novel shines when exploring humanity’s recovery after devastating loss, balancing large-scale ideas like terraforming, advanced civilizations, and faster-than-light travel with personal relationships and resilience. The pacing occasionally slows under the weight of scientific explanations, and some readers may find the exposition heavy. However, fans of idea-driven sci-fi will likely appreciate the depth and optimism. Overall, it’s a thoughtful and engaging continuation that rewards readers invested in Alex Durant’s journey and the broader universe. � literarytitan.com +1
Tachyon Tunnel 4 is another exciting story continuing the story of Alex Durant. The book continues to develop Durant as well as his "daughter" and his partner. They are all complex characters that you can really feel some attachment to. The author does a fantastic job at building and maintaining this complex world with solid scientific principles instead of huge leaps from logic like many sci-fi novels. This book does rely heavily on the assumption of the theory of evolution, so that would be a caution to those who do not want that kind of content. Overall, interesting and very compelling read.
Tachyon Tunnel 4 delivers another fast, high‑energy leap through Michael Gorton’s expanding sci‑fi universe. This installment sharpens the stakes, pushing characters into deeper moral and temporal conflicts as the consequences of time manipulation finally hit full force. Gorton balances scientific imagination with emotional tension, making the story feel both cosmic and personal. The pacing is relentless—sometimes almost too quick—but it keeps the narrative gripping from start to finish. Fans of the series will appreciate how threads from earlier books tighten and twist, setting up an even bigger payoff ahead. A satisfying, momentum‑heavy continuation that refuses to slow down.
Tachyon Tunnel 4 picks right back off where it left off in Tachyon Tunnel 3. Fast paced and jam-packed with futuristic technology mixed with a dash of science fiction, this series is great for the science tech lovers who need a little escape from reality. I got a free copy of this book and as a self-proclaimed sci-fi novice, I found myself being pulled in from the very beginning. I gave it only four stars because I would have appreciated a bit more exposition/review from the previous book in the beginning for those who didn’t reread the third book before starting book four. Otherwise, great writing!
Michael Gorton has brought to life a wonderfully creative, beautiful yet terrifying, view of the Universe.
Characters are 3 dimensional, fun, interesting, and easy to care about. Even the robots!
Based on real science, Tachyon Tunnel 4 is intense, exciting, and richly detailed. Catastrophic problems are addressed with mind-boggling creativity. Fascinating inventions foreshadow things possibly to come.
Heartily recommend Tachyon Tunnel 4, and the whole series. Would love to see it made into a series of movies!
I love science fiction, especially science fiction movies and this book literally was like a movie in my mind. The author was definitely invested in describing the advancement in technology and the consequences. I was able to follow along and I really loved learning new things as I read the book. Alex and the predatory Daklin Empire with navigating Mars all brings back the feels of the 100 mixed with lost in space. The chaos is palpable! It is not a quick read and you need to be invested to love it however, it is worth it! 💯 recommend!
Tachyon Tunnel 4 is an innovative space adventure filled with powerful scientific insight and realistic human connection. With the tachyon tunnel technology, people are now able to travel through time and space in the blink of an eye. They've learned to harness the power and energy given off by stars, rebuilt civilizations, reshaped planets and fought for survival. With the scientific revelations comes the realization that power always comes with a price. As this story unfolds, the deeper truth begins to be revealed, as they battle the Daklin Empire.
I received this book for free, and this is my honest opinion. I haven't read the previous books in this series, but reading this book has made me want to. The instant the book starts, you're thrown into the aftermath and chaos of this world. My heart was broken for these people, and I was sucked into their story. Though this is four books deep, I had no problem following along with the story, and that made me extremely happy. I'm intrigued by this world and want to know it better. This is science fiction at it's finest. I can't wait to read the other books.
Tachyon Tunnel 4 by Michael Gorton continues the story of Alex Durant and his team after they beat the Daklin Empire. The book mixes cool space travel using tachyon tunnels with real science that is easy to understand. There is lots of action, big ideas about the future, and questions about power and what happens when civilizations get too strong. I liked how it mixes adventure with deeper thoughts about history and rules that control advanced societies. It kept me interested the whole time and made me want to read more of the series.
Another awesome read by Michael Gorton. What completely hooked me about this book wasn’t just the crazy-cool planetary engineering or the portal technology—it was the deeply human story at its core. It’s a beautiful, raw look at a family trying to navigate grief, loss, and the fragile bonds between parents and kids. The author does such a perfect job balancing massive, sweeping space-opera stakes with these quiet, realistic character moments. It gave me the perfect mental escape while still being a deeply thought-provoking, beautiful story of survival.
