A new adventure based on the thrilling Paramount+ TV series Star Strange New Worlds !

When murder and sabotage imperil the time-sensitive and top-secret mission of a team of civilian scientists, Starfleet deploys Captain Christopher Pike and the Enterprise crew to Kathara Station, a classified research facility located above the accretion disk of a black hole.

Lieutenant Commander Una Chin-Riley soon discovers the station’s director, Valkeya, is hiding secrets—but so is Captain Pike, who many years earlier visited this same black hole on a mission that went tragically wrong, and whose consequences have haunted him ever since.

Caught in the crossfire on the station are Science Officer Spock, Nurse Christine Chapel, and Security Chief La’An Noonien-Singh, whose romantic entanglements old and new threaten to unravel their bonds of friendship.

As enemies converge upon the station, can Valkeya and Pike both atone for the mistakes of their pasts in time to avert a tragedy? With time running out, the survival of Kathara Station, the USS Enterprise, and dozens of innocent lives hinges on their acts of contrition.

David Mack returns to Star Trek with his second hardcover (first was Firewall). He's written dozens of Star Trek books at this point, and he has quite a range of quality, going from absolutely top tier incredible to good to meh to not good.

And I'll say this is his best book in about a decade!

This book is part mystery, part thriller, and is science based regarding the wormhole and accretion disk element of the story. I feared that I would not follow the science and be lost, but David Mack did an excellent job explaining what the science meant and I was able to connect it to the story.

The story of this book is so much shrouded in mystery that it becomes difficult to talk about it in a review. What I'll say is that some of the story had 'predictable' moments, but only because I caught on to some of the groundwork that Mack was laying. Yet there were other elements of this book that were shocking to me, and I really enjoyed exploring that mystery.

The book is paced very well, and I loved having a crew on the station near the wormhole and a crew on the Enterprise which couldn't send help. It made the story very relatable and I completely empathized with all of the difficulties that Pike is going through in the book.

That being said, I was a bit nervous when chapter 2 came in and was all about the crews feelings and relationships. Fortunately, the rest of the book goes in much more of a classic Trek story direction and makes up for it. And I will admit I do appcreiate the focus on more traditional relationships here.

There are some curious story points, particularly with the mystery of the murderer and the saboteurs that I thought were odd, but despite that I was still hooked reading the story.

Mack has had a string of good or ok books in the last decade, but this was the first book since reading A Ceremony of Losses and the Destiny Trilogy that I was hooked for the entire book. Mack really took a risk with this book and I think it absolutely paid off! Overall, 9 out of 10!

Star Trek: Strange New Worlds: Ring of Fire is a novel that is strangely alike the previous one in the series. We have in common: an away team in danger and cut off from the Enterprise, the Klingons making an appearance to complicate things, Ortegas playing a prominent role, time travel etc. But Ring of Fire stands on irs own and is even better.

Star Trek: Strange New Worlds – Ring of Fire by David Mack
⭐️⭐️⭐️⭐️ (4/5)
A stellar tie-in that deepens the series’ emotional gravity

David Mack delivers a taut, character-driven thriller that feels like a lost episode of Strange New Worlds—one that trades warp-speed spectacle for psychological depth and moral reckoning. Set against the backdrop of a black hole’s accretion disk (yes, the stakes are cosmic), Ring of Fire plunges the Enterprise crew into a web of sabotage, secrets, and emotional fallout.

Captain Pike’s haunted past collides with the present in ways that test his leadership and humanity. Una Chin-Riley’s investigation into Kathara Station’s enigmatic director, Valkeya, crackles with tension, while Spock, Chapel, and La’An navigate romantic entanglements that feel earned, messy, and very human.

Mack’s prose is brisk but layered, balancing technobabble with introspection. The novel doesn’t just expand the show’s lore—it interrogates it. What does redemption look like when time is running out? Can friendship survive the gravitational pull of guilt and desire?

While the pacing occasionally stutters under the weight of exposition, the payoff is worth it. Fans of the series will appreciate how Mack honors the ensemble’s emotional arcs while introducing new dilemmas that feel tailor-made for the screen.

🖖 A must-read for Strange New Worlds devotees craving more depth, more drama, and more black hole metaphors.

Happy reading and live long and prosper 🖖 📚

I happened to be finishing up my previous read, which happened to be another Trek novel, on the day this dropped... so of course I dove right in.

I enjoyed this story and I made many out-loud chuckles while reading.

Enterprise gets sent to assist at a top secret research station, after a murder and some sabotage has occurred. Station command try to hold onto their top secret, secrets für a little too long, thus hindering the work of the Enterprise teams.

Right when I first felt like the story was wrapping up, I checked and there was still over 2hrs on the player. I'm sure it continued past what I'd presumed where endings another three times.

Sabotage on a Daystrom Institute sponsored research station leads Starfleet to assign the 'Enterprise' to investigate. To their surprise, it appears as if this could be a temporal event that was caused sixteen years ago by a young Lieutenant Christopher Pike.

Mack has written a good 'Star Trek' mystery story, where the characters fit well. Indeed, the characters drive the plot and come to life extremely well on the page.

It's a perfectly solid story, and everyone is well-characterized...yet I found myself feeling "meh" at times, and I'm beginning to wonder whether I'm getting bored with the "Strange New Worlds" universe. I'm missing the excitement and intensity of "Discovery" and I'm looking forward to an entirely new look at the future with the upcoming "Starfleet Academy"...and all this feels rather static and ordinary by comparison. Something to think about...

Ring of Fire is one of my new favorite Star Trek novels. Set within an arguably uneven season of Strange New Worlds, this is the story the show's fans deserve. David Mack delivers a gripping, character-driven, and emotionally charged adventure that perfectly captures the heart of this crew and the spirt of Star Trek.

The pacing is fantastic — especially the last third, which is a full-on, edge-of-your-seat thrill ride. Mack absolutely nails the characters' voices. It truly feels like watching an epic two-part episode of the show, but with more time to explore the characters in depth. Everyone gets a chance to shine, making this a true ensemble piece — something that's sometimes missing from the series and other novels. Even the side story with Pelia and Scotty, while occasionally harsh on Pelia's part, ends up giving Scotty some well-earned moments of brilliance.

The central story — Pike confronting his past while balancing a high-stakes mission above a black hole — is one of the most compelling Strange New Worlds plots to date. I'm talking across both the series and the novels. It's strange at first to see Pike so vulnerable, but Mack uses that vulnerability to give him genuine growth. His prior mission sixteen years earlier might feel a little convenient at first, but by the end, it makes perfect sense why Pike had to be at the center of it all. Meanwhile, Una Chin-Riley's investigation with Valkeya unfolds like a classic mystery, revealing its secrets slowly and keeping readers guessing who they can trust.

While I didn't completely follow the murder, sabotage, and Klingon subplots, they work as a clever MacGuffin that moves the larger story forward. These are the plots that provide the crew with situations that push them out of their comfort zones and let them grow. That's what great Star Trek stories do — they test the characters' limits while reaffirming their humanity.

It's also refreshing that this book mostly stands apart from the show's continuity. Other than a few brief references for context, Ring of Fire is a self-contained story — and a stellar one (if you'll pardon the pun). Pike gets out of his head about Batel, we avoid certain uneven elements of the season, and the result is the kind of standalone adventure Strange New Worlds promised us from the start.

Fast-paced, character-rich, and full of heart, this is Strange New Worlds at its best. It's accessible enough for new comers and deeply rewarding for long-time fans. For me, Ring of Fire ranks among the very best Star Trek tie-in novels and stands as one of David Mack's finest. It's every thing tie-in fiction should be: a great in-universe story that gives its characters room to grow and deepens our love for the source material.

And if there's any doubt at this point, I gave this book a full 5 out of 5 stars!

If you like action movies with lots of explosions, only limited character study time, no fluff, and more plot twists than anyone could count, AND don't mind the "This could have been a story of 5 pages if people would just communicate properly" trope, this book might be for you. Unfortunately I enjoy none of these things. In fact I love my Trek best when it's sociological or at least diplomacy based with lots of fluffy found family feelings. If you're like me, this book is not for you and I will tell you more reasons in the spoilers:

There are those who say media tie-in novels (such as Star Wars or Star Trek, for example) aren't as good as "original" novels. That tie-in novels are somehow "less than".

After the original Star Trek TV series was canceled in 1966, I started reading the Star Trek tie-in novels. Obviously, there were a lot of Star Trek fans hungry for new Star Trek stories so the decision was made that more Star Trek books should indeed be published.

At first, I read EVERY ONE that came out. Then, I have to admit, I DID notice that some were markedly better than others. At that point, I became more selective and paid more attention to the names of the authors on my Star Trek books.

Well, I'm here to tell you that most Star Trek books are OK, some are better than others, and some are amazing! This new book, Ring of Fire by David Mack, is definitely amazing.

I knew that I had wanted to read Star Trek books by David Mack, but I had not consulted my notes to see why this particular author sounded good to me. Then, when I did look after finishing Ring of Fire, I found out that he had written Firewall (my favorite Seven of Nine book, set during Star Trek: Picard). Another amazing Star Trek book.

Ring of Fire is a richly imagined book, albeit in the Star Trek world with the Star Trek Strange New Worlds cast. Again, because Strange New Worlds is relatively new (fans have only seen the first three of what are supposed to be five seasons so far), there is still room to flesh out some of our favorite characters in this cast.

A stirring not-to-be-missed Star Trek Strange New Worlds adventure awaits fans in Ring of Fire. I can't wait for David Mack's next Star Trek SNW book!

Highly recommended for all Star Trek fans, all Star Trek Strange New Worlds fans, and also hard sf military space opera fans, as well!

David Mack's. "Ring of Fire" is a book that means well from a plot standpoint but goes so far off the rails to explain things that it makes this one of his more challenging novels which is a shame. The plot revolves around an emergency involving the mystery of Kathara Station which is situated near the event horizon of a black hole; however, the station's director along with everyone else aboard seem to be hiding secrets which are jeopardizing the mission. This system is also home to a command decision Pike previously made which haunts him to this day. Mack's characters themselves are well written, and we the reader understand the gravity of the emotions that all of them are feeling. It does though take far too long for the flashbacks throughout the book to explain exactly what we are dealing with which does harken a bit back to the Temporal Cold War days referenced in "Star Trek: Enterprise". There is also the unnecessary threat posed by a Klingon ship that becomes a plot device to try to extend the book. The ending itself is a bit weird as well once all the pieces are put together, but overall this is a plot mess that Mack himself can't seem to solve in a book that should've been far shorter than what it is.

I thought that the story was interesting, fun, and well rounded. I had to suspend my disbelief, but such is the way. I'm not reading Star Trek novels for accuracy. I was incredibly disappointed with how the female characters were written in the novel, and how they always needed to be saved or coddled. I get it, we all love Spock ok? But why was he ridiculously strong and always saving the women? Maybe I'm just a freak but sometimes I want the big strong man to have to get saved. I also have no problem with weird sudo-love triangles and messy friendships, thats the joy of officially sanctioned fan fiction. It was just interesting, given that in the show (strange new worlds, not other start trek series) all the Spock centric episodes are mainly comic and involve people helping him discover things about himself and identity (My point is that he often receives or needs help from his friends, which is a main topic in his storylines and emotional journey). I get that everyone has there own interpretation of characters like Spock but this book felt sexist, which is disappointing.

Can’t fault the characterizations or the pacing.

I’m puzzled about the saboteurs. Did they find out about the project, *then* embed themselves at the Daystrom Institute? Or were there already spies from non-Federation worlds there, and they sniffed out the project they thought would be most damaging to their respective homeworlds? Perhaps they knocked on an airlock and asked if Kathara Station was hiring?

Either way, Valkeya seemed quite cavalier about the lives of of the research station personnel-- except for her husband. As long as the mission was carried out successfully, it was fine if everyone on the station died. Further, having finagled help from Enterprise, she viewed it as expendable as well.

Given that attitude, I was surprised at Una’s willingness to forgive Valkeya’s actions and keep her secrets.

High Country remains the best of the SNW novels so far.

physics?

The book was okay, but it really bothered me that there were no time dilation effects from being so close to the high gravity of the black hole. Time is affected by gravity to the extent that time passes at a different rate on the International Space Station compared to Earth, so I imagine there would be a much greater impact practically touching the accretion disk.

Also wouldn’t there be intense forces on the ship and station?

The second thing that bothered me was crisis after crisis. It seemed kind of overdone to me, maybe to just increase the word count. I thought the book was coming to a close and then realized I was only about halfway through it. Sheesh.

The book surprised me because the previous three books were pretty good.

Ring of Fire may not be the epitome of what a Star Trek novel could aspire to be—if such a thing exists—but the plot unfolds as a captivating high-stakes thriller, brimming with the essence of Strange New Worlds. Mack, with his well-honed craft, delivers an enthralling character-driven saga that maintains our rapt attention. If only the Paramount+ series shared the same level of thrill, Trekkies could dare to dream of more.

I've always enjoyed David Mack's work in the Trek space, and this book was no exception. The plot was (intentionally) frustrating, filled with bureaucracy and secrets getting in the way of a mission, and it felt realistic both in the present and Star Trek's future. The SNW characters were all well written and felt true to their on-screen counterparts (with La'an/Spock giving me the ick exactly the same as it does on screen, even, lol). I love a plot that involves temporal mechanics, and this one hit all the right notes. Really solid book all around.

I know many of you are neither Sci-Fi fans nor Trekkies but you are missing an opportunity if you don’t give Ring of Fire by David Mack (★★★★) a go. From the Star Trek Strange New Worlds storyline this book was a thrilling ride and did a great job diving into the psyche of the characters. It was arguably the best Star Trek book I have ever read.

If you like the show, even a little, dont even think on it… get the book.

If you opt for the audiobook, Robert Petkoff was excellent and there are none better at bringing the star trek universe to life.

There’s the thing I love about these books.
They just understand characters and provide more of a beautiful character dynamic.

Honestly this one made Scott’s and Pelias companionship more interesting, and kinda funny. Plus a lot of this reminded me of the Vanguard books

All in all,
Fun, interesting, and just fantastic.

This one hits the ground running and doesn't let up until the very end! I like how all of the main characters get a moment to shine. I particularly liked how Ortegas got to stretch within the story. And the mysteries unfold in some fun and surprising ways. This could have easily been a top-tier episode of the series. Highly recommended to anyone who is a fan!

I really like when the story gets more introspective, with stuff like Spock questioning his relationship, Chapel being worried about her friendship with Spock, and Pike opening up to Una about the past where lives were lost because of him. The stuff about the horse was too sad to read about. This is also firmly set before the weird documentary episode.

Enjoyed this book overall. It has a mystery with SiFI twist. My only criticism is exploring the Spock-La’an-Chapel love triangle. I don’t mind Trek romances but it was my least favorite part of season 2 and of this otherwise good novel.

I enjoyed the story and am always pleased to have the option of reading another SNW book. However, the level of hazing involving certain engineers, seemed entirely unnecessary and inconsistent with my expectation of how starfleet members would behave.
