Perun's Hammer: A Novel
“One of the best books that I’ve ever read!” -Kent Rominger, former Space Shuttle Commander / NASA Chief of the Astronaut Office
What if you received a video showing exactly what happened to Amelia Earhart?And then similar videos of the Battle of the Little Bighorn and the Tulsa Race Massacre? What would you do if historians and experts verified every detail, and none of the videos showed traces of CGI?
If you’re Rich Penton, lead reporter at the investigative news show, RECON, you’d try to figure out who made the videos, who sent them to you and what you’re supposed to do about them. The only thing you’d know for sure is that the existence of the videos is absolutely impossible.
For humans.
But when the RECON team receives a video showing Chicago destroyed by an asteroid in the near future, they decide they’d better take it seriously. That’s when they feel the full force of the U.S. military and intelligence agencies, which clearly don’t want RECON involved in whatever mess this is, and the Russians send an assassin to ensure that anybody who tries to broadcast the videos winds up dead.
Perun’s Hammer blends exciting and contemporary AI, foreign intrigue, murder, historical mysteries, hazardous asteroids, undercover agents, a bizarre cult, and a mysterious intelligence that seems to be able to see through time.

Interesting SF Concept
A decent time travel mystery with varied characters. The character pacing was a bit hurried overall and character development was marginal. Still, the story is engaging and intriguing enough to invite you along, though with one BIG caveat: tying EVERYTHING to a fault to the author’s present day social mores.
Out of the gate, the cast of characters are introduced as diverse, socially aware and entirely progressive (aside from one who serves as a proxy ideological convert). The author painfully and repetitively speaks essentially through the fourth wall to re-remind you of each character’s social virtue, to the point where it breaks immersion and detracts from the story, and several times almost stopped me in my tracks from finishing the book. This side narrative is so strong and presented as so virtuous, that it leaves no room for the reader to organically chose to side and identify with the characters, and if you don’t, you know right away what the author would think of you. The author uses his voice and characters to write his personal social views into the book at the expense of the story. The narrative effort is not deft, it is heavy handed and increasingly predictable as the story progresses.
The historical and science research is great and well described, but again is undermined by the heavy handed messaging it is meant to convey—with each main character promptly being written to applaud it in every such scene.
The antagonists are two dimensionally evil and presented regularly with scenes of violence and moral depravity. It has very mixed effectiveness and falls into the same narrative messaging, dragging the story down.
Great real world locations and presentation, interesting storyline, decent characters in many ways, but overshadowed by relentless real-life messaging. It’s akin to preparing a great smelling soup and just as you serve it having the top of the salt shaker fall off and dump the whole thing into the pot.
I would rate the story as a solid three-and-a-half if the author had simply let the characters and story speak in their own voices.

5 Stars. One of the best books I've read this year.
When I first started reading this novel it seemed to be like Phillip Dick’s, The Man in the High Castle, with the detailed videos of something that wasn’t explainable in present terms. Some of the historical background information revealed was interesting (Custer & Ehrhart) and some were distressing (Tulsa & WWII). The explanation given regarding relativity and time travel was easy to understand, and (for me) harkened back to high school physics class.
Throughout the story there is this overarching mystery: Where is this information coming from, who/what is this “intelligence”, and how did these mysterious beings produce these realistic videos? The characters themselves seem like everyday people caught up in a situation they can’t untangle themselves from.
As some reviewers have indicated, they liked this author’s style of writing and look forward to his next book in this series. I concur. I too was impressed. You know it’s great when you read a book that: (1) Really captures your interest throughout the story, (2) Has good to excellent, intelligent dialogue with realistic problem-solving, and (3) Has an intriguing mystery to it. Well done.

I highly recommend this outstanding book! As a first-time novelist, the author brilliantly blends history, human drama, sci-fi, and an understandable treatment of contemporary technologies into an engrossing story. I enjoyed the nudge provided by the book to go out and research historical events of which I had limited knowledge. I also liked the reference to Slavic versus more familiar mythologies. The story resolves cleanly, while creating the context for future novels in a series. Can't wait for the sequel!

So I had to sit for several hours in a car dealership waiting room while I had some work done on my car. An ad for this book came across my facebook feed. It sounded interesting and since it was on kindle unlimited, I went ahead and got it. Really glad I did. I read about half of it while waiting and the rest when I got home. A sci-fi story that had some elements of a spy novel and some discussions of actual historical events. I really enjoyed it and highly recommend it if you want a quick and entertaining read.

Great Story
Nail biter with more twists than Arkansas backroads. Might be worth a sequel? Great likable characters with thoroughly hateful villains.

I wish I could give this book 10 stars!
This is a truly excellent story with wonderful characters and a story presented in a believable way. There are so many nuances to the story… it’s not strictly science fiction nor a historical story but there are elements to both in the book. I highly recommend it and look forward to the sequel.

Person's Hammer
Wow! What seemed like another catastrophe yarn, became something else entirely by the end of the first chapter. I RARELY give 5 stars to any of the many stories I read. But this one deserves it and I highly recommend it for entertainment.

May 27, 2026Wow! I normally have 4 or 5 books going at the same time. Two pages into this one, I couldn't put it down. Almost anything I said about the story would give away too much. Suffice it to say that it is the best book I've read in a long time and I would recommend it to everyone.

I received a free copy of Perun’s Hammer through a Goodreads Giveaway. I found it to be a very enjoyable science fiction read. The characters were well developed, the pacing kept me engaged, and the story held my interest from beginning to end. One aspect I particularly enjoyed was the incorporation of historical events and figures into the narrative. I wasn’t expecting that element, and it added an extra layer of depth and intrigue that made the book even more engaging. The blend of science fiction with historical references felt fresh and thoughtful

Once I started reading this book I couldn’t put it down. This book had so much depth. It went through many different historical events and gave you a Birds Eye view of what happened all those years ago. The team investigating these events was interesting in itself and made me want to keep reading. I love that the author brought up some historical events that many would shy away from especially now. I suggest everyone read this amazing book.

An exciting story of a meteor (or something!) Streaking toward earth, it is too far away for any sensors to detect it; the only warning is via a mysterious collection of videos that appear out of nowhere. As a group of journalists(?) rush to prove the things existence, various bad guys try to stop them. Interesting twist on disaster stories.
February 20, 2026
It begins with the impossible delivery of an equally impossible video – even if all that Rich Penton and his crew at RECON are certain of at that point is that the delivery shouldn’t have been possible. The video looks like REALLY good CGI of a meteor crashing into downtown Chicago. RECON is a successful, award-winning news magazine TV series (sorta/kinda like 60 Minutes was back in the day) but based in Chicago and set in the mid-2020s.
Meaning that the team at RECON is used to getting unusual pitches for stories. And that they know all about cutting-edge CGI. But it also means that their network security is state-of-the-art, a state that means that videos should not be capable of ‘magically’ appearing in anyone’s email without getting checked. And it certainly means that once such an email is deleted – it STAYS deleted.
The painted picture on this bison hide shows the battle of the Little Bighorn, where the Plain Indians fought Lieut. Col. George Custer’s troops. By Cheyenne artist – Museum of the American Indian
Except this video isn’t behaving the way it’s supposed to.
Not that they can do anything with it or about it except for the security breach. There’s nothing attached to tell them who sent it, how it was filmed, or what the purpose of it might be. They assume it’s a pitch for something – they get those all the time, but usually with a lot more information than this.
Then the second video arrives, just as mysteriously as the first. A video that seemed to have been taken at the Battle of the Little Big Horn as it was happening. In 1876. A video that checks out in every particular except one. In spite of repeated attempts to figure out how it was made, there is ZERO evidence of it being CGI. It seems to be authentic right down to facial recognition of even minor characters – even the angle of the sun and shadows is not just internally consistent but consistent with the date, time and location of the battle.
Tulsa Race Massacre aftermath, June 1, 1921
Which is when Rich and his team at RECON start to really, really dig. Because one way or another, this is one hell of a story. But as videos keep coming in, from Amelia Earhart’s ultimately fatal crash in 1937 to the horrors of the 1921 Tulsa Race Massacre to the tragic 1945 bombing of three German ships, the Deutschland, the Thielbek, and the Cap Arcona, filled to the gunwales with Jewish concentration camp inmates who were either killed by British bombs, or from being clubbed to death by Nazi soldiers and sympathizers waiting for the few survivors to wash up on shore.
As each of the later videos gets a YES in the column for historical accuracy and a NO in the column for being provably some sort of advanced CGI, it brings questions about the purpose of that first video of a meteor or asteroid striking Chicago, into terrible focus. If all the other videos are real recordings of historical events, then what was that first video? Was it a warning?
And if it was a warning – can they get the right people to believe in something so seemingly impossible in time to change the future before it becomes the present?
Escape Rating B+: First of all, in the interests of full disclosure, I received this book in a “friend of a friend of a friend” situation. Which I was honestly a bit salty about as I’m not all that fond of being committed to things by proxy.
Howsomever, (knowing this will completely undercut any and all arguments with the friend who got me into this), I’m not at all sorry about the whole thing. In fact, I’m pretty damn pleased with the result now that I’ve finished the book – and in spite of the quibbles I’m going to throw in near the end.
I had a damn good time reading this. Seriously. It was a thrill-a-minute ride from beginning to end in the best sorta/kinda SF movie thriller tradition. Movies like Armageddon, and Deep Impact.
What made Perūn’s Hammer just a bit different, and a whole lot more fun from this reader’s perspective, is that the story is set recognizably in Chicago. Not New York, not Washington DC, but Chicago. As someone who lived in Chicago for several years, I could picture all the scenes in the story AND just how big the devastation would be.
Which leads directly to the second fun thing. In most disaster movies, the disaster has either already happened or is past the point of no return. A big part of the plot and the point of Perūn’s Hammer is that those videos represent a future that ‘might’ be, not a fixed point in time. The worst of the crisis could be averted – if humanity can get its act together in time.
So the story isn’t the dystopia that comes after, or even the planning vs. panic scenario of an inevitable onrushing catastrophe. Instead, the ticking clock that drives the action is the investigation to figure out the nature of the message and then the mad scramble to act BEFORE it’s too late.
Neither of which could possibly be the job of a single human being – so even though parts of the story are told from Rich Penton’s first person perspective – which admittedly cuts the tension a bit because we know he survived otherwise he wouldn’t be around afterwards to do that telling – much of the story is told from a third person overview in order to follow the workings of the stellar team that make the show – and this story – possible.
Their team dynamic is absolutely top-notch. Each person is at the top of their respective game, and they each do their part to solve the mystery. It’s going to be up to Rich to convince the powers-that-be to put a multibillion dollar asset into space in the hopes of knocking the object off course. But he needs their collective very able assistance to put it all together and the investigation in all its many facets is a joy to follow.
Unfortunately, this is where my two huge quibbles with the story come in, and together they were enough to knock this from an A grade to a B+. Because I was compelled, but also extremely annoyed at this part.
In order for the reader – and the team – to truly appreciate just how high the stakes are in this story, one of the team members had to die. That’s the way thrillers like this work and it wasn’t exactly a shock for the reader when it happened. Especially considering that as far as solving the mystery goes, this particular team member had already completed their role. The problem I had with this was not the death, but the choice of character to die. The team member who was killed was the only gay person in the central cast, and the only character who was not or did not become part of a romantic couple. The “Bury Your Gays” trope is basically a cheap shot that did not need to be part of this story. Or, for that matter, any story.
It also leads directly to my other issue with the story, and that’s ‘villain fail’. There is a villain here. They’re not the ones who launched the object, but they are the ones trying to take advantage of it. In the international political climate of the past few years, the idea that the Russian Federation might be gleeful about an interstellar object flattening Chicago isn’t quite out of the bounds of plausibility. That Russia would engage in a campaign of misinformation and bribery in order to prevent the US from launching countermeasures in time is also not that far-fetched. Nor is the idea that they would have agents in the U.S. working to protect such a plan. However, the idea that all of that happened AND that the specific agent involved embodied all the worst possible racist, homophobic, sexist, psychopathic, sociopathic, violent and outright ‘bwahaha’ villain characteristics that have ever been assigned to a negative portrayal of an enemy agent in a single person put the whole thing way over the top and tripped my willing suspension of disbelief completely. To make a long harangue into a short sentence, the character of the villain of the piece slipped WAY over the line from CHARACTER into CARICATURE.
Amelia Earhart standing under nose of her Lockheed Model 10-E Electra. Gelatin silver print, 1937 by Underwood & Underwood
Very much on my other, and much more fascinated hand, I loved the deep dive into the historical incidents that were part of the vetting process for the videos. I wanted to say ‘happy’, but that’s the wrong word in this case. The historical analysis read as in-depth and extremely well done, which is something that I always love to see. However, I think it is important to note that all of the historical incidents with the exception of Amelia’s Earhart’s most likely sad end, were all true events that were horrifying in the extreme. They were also outright brutal tragedies of human inhumanity to other humans that were swept under the historical carpet because the victims were considered “other” from the perspective of the powers that be at the time.
A lot of the SFnal aspects of Perūn’s Hammer have been done before, in stories that reach as far back as Niven and Pournelle’s Lucifer’s Hammer through Kowal’s Lady Astronaut series and all the way up to last year’s When the Moon Hits Your Eye by way of at least two of the Star Trek movies (TMP and IV) as well as those disaster thrillers I started with. Those familiar SFnal elements blend into a story that will keep readers on the edge of their seats, whether the parts that appeals are the historical mysteries, the technical breakthroughs, the political shenanigans and the spy games, or the surprisingly open-ended conclusion.
In spite of my quibbles, I had a grand time with Perūn’s Hammer. I think those quibbles hit so hard BECAUSE I was having such a grand reading time and those flaws disappointed me in a book that was otherwise really terrific.
All of which means that I’m glad that the author has already promised a sequel, tentatively titled Perūn Rises. I’m looking forward to seeing what happens next.

March 31, 2026Tapped out at 68%. A lot of token wokeness. The pace has picked up a bit at the 60% mark, but by now I just don't care.

Excellent combination of character development, action, and hard science.
As I said, there is an excellent combination of character development, solid action, lines, and hard science in this novel. Custer, Greenwood, Nazis and Russians, add a lot of spice to the storyline.

This was a wonderful read. The characters were interesting and fleshed out. I really like how important historical events were woven into the story. I am greatly looking forward to reading the sequel

Fun Read
This novel was about humans in Chicago receiving emails/videos from an alien life form warning that Chicago was going to be struck by an object from deep space. The characters were likable and interesting, as was the final outcome. The sequel should be interesting too.

What an excellent, well-written SciFi book! Hurray! Go get This Title and Read ASAP!!!
This was an enjoyable book, and difficult to put down once you’ve started reading it. The SciFi parts include a healthy imagination, mixed in with real-life science, spacecraft, human and ExtraTerrestrial (ET!) capabilities … what more could you ask for?!? Well, OK, there’s also terrorism, clandestine spies, and the wife of the main character, who is losing her mind (and, perhaps, The Author’s interactions with this woman are the weakest points of the story).
And, admittedly, this Reader simply did not understand an audio recording that The Author felt was important, and played near the very, very end of the book. Unfortunately, The Author makes no attempt to clarify WHOSE voice was in the recording … oh, well.
No matter what — go get this Book and read it ASAP!!!

Excellent topic treatment and character development of intertwined plots. Can't wait for Perun Rising, the sequel. .Having spent most of my career in the space business, the satellite communications scenarios are highly plausible.

great read
Loved the story, character development and historical details. Enjoyed the flow of the story and was satisfied with the ending cliff hanger. When can we expect the next installment.

I wish all Kindle unlimited sci-fi were this legitimate
Relatively hard sci-fi with deeper than usual characters. The title is clearly an homage to Lucifer's hammer. Plot and the various aspects of conflict were serviceable. The behavior of various governmental entities and personnel were simplistic and not very believable but I don't care, if I wanted to read about politics I wouldn't be reading escapist fiction. Speaking of which, I think the author did a largely good job of keeping his own political views and observations to a minimum, a super welcome departure from almost every instance of media we hear and read and watch. The only one that irked me was comparing the Tulsa race war/massacre to unspecified events in modern America, which I thought cheapened the horror of the Tulsa events in exactly the way the author obviously intended not to do. Aside from that and one or two other peeves, this book is exactly what I'd like to see more of: old school science fiction in 2025. Well, 2026 now. It's almost like we're living in the future.

Easy and fun way to learn!
This book is action-packed with a fascinating plot that will appeal to science and history nerds as well as those just looking for an entertaining read. I loved the creative story hook, which is built around videos of historical events that suddenly begin appearing on phones and computers. The memorable and engaging characters have to work together to try and solve the meaning of the videos, against a ticking clock, with Armageddon-level stakes. Along the way the author teaches us about everything from time travel to quantum theory to “what happened to Amelia Earhart” in an accessible way. Read it. You’ll have fun and likely get smarter in the process. I did.

This book was recommended to me by my West Point Classmate turned author Mike Slavin. I loved this book. It is incredibly suspenseful. And also an incredible combination of WHAT IF and Sci Fi - involving not people ravelling back and forth through time, but rather something more plausible - information travelling back and forth in time. The author weaves together murder with undercover three-letter agencies, Russian foreign agents, hazardous asteroids, and cults - all centered around a mysterious non-human intelligence as the back cover suggests 'that seems to be able to see through time."

This was better than the dozens of similarly themed thrillers that went before it. Yet, it also remains a pulp fiction page-turner, if better written than serials I read in the waning days of pulps in the 1950s. No time was wasted on the panic in the streets or the clogged highways out of town. That would have been a cliche. Instead, we have conspiracies to threaten the media team at the center of story and their shadowy protectors. And, there’s a surprise reveal in the final pages.
