The Sword of Cyrus: A Conspiracy Thriller Where History Fuels Modern Warfare (A Rossler Foundation Mystery Book 4) Kindle Edition
A weapon smaller than a phone. A threat larger than civilization.
Deep in the Zagros Mountains of Iran, a secretive group calling themselves The Sword of Cyrus has engineered the ultimate weapon—a nanotech nuclear device small enough to fit in a mobile phone yet capable of unleashing the force of seven Hiroshima bombs. Its purpose? To wipe Western civilization off the map.
For Dalir Jahandar, vengeance is more than a mission—it is his destiny. A descendant of kings, he is determined to restore the ancient Persian empire to its former glory. Just as Cyrus the Great conquered Babylon by outwitting his enemies, Dalir and his secretive network of powerful allies will infiltrate their enemies from within, striking when they least expect it.
Daniel and Sarah Rossler, along with their team at the Rossler Foundation, find themselves at the forefront of the battle. Known for their work in archaeology and cutting-edge science, the Foundation is drawn into a global conspiracy where history, technology and warfare collide. With Dalir’s operatives closing in and time running out, they must navigate a treacherous landscape of espionage and betrayal to stop the unthinkable from happening.
Will the Rossler Foundation prevail, or will the world succumb to the devastating power of the Sword of Cyrus?
The Sword of Cyrus is the fourth gripping installment in JC Ryan’s acclaimed Rossler Foundation Mystery series, where ancient ambitions meet modern warfare in a high-stakes battle for the future of civilization.

Review
D.J.(Psychol),Chester,UK Amazon Reviewer - The pot at the end of the rainbow. The perfect culmination to a series of books which offer a master class in the writing of'thrillers' with an archaeological background.
J.C. Ryan, writing with a deceptively minimalistic writing style, creates story lines and characters that the reader cannot help caring about,set in carefully researched scenarios. His four books to date clearly deserve the attention of Hollywood looking for 'block-buster' films, but those of us who prefer the written novel will realise that this series of 'Rossler Foundation' books will become a classic in the genre which seeks to appeal not only to those with a passion for archaeology, but also those with an interesting the immediate future. Read all four books to gain the maximum benefit! You will not be disappointed. It is to be hoped that J.C. will continue to mine the seam of gold he has created.
Deborah Stachowiecz Amazon Reviewer - So Glad I Persevered And Read Book 4. My journey through the Rossler Foundation series was almost derailed by my reaction to the storyline in Book 3! The author used his excellent writing skills but for some reason there was this dark bleakness for me in the very plausibility of the central pandemic scenario. Though I gave Mr Ryan full marks for his characters again, I wasn't sure I could face another such dark story in Book 4.
And when I encountered the deep and abiding hatred used to logically fuel the "why" behind Book 4's villainous plot, my heart once again dropped. ISIS' despicable actions in the evening news showed Mr Ryan's premise was quite in line with extremist sentiments.
So instead of sailing through Book 4 in a matter of a few hours, I kept just dipping a toe in and then finding some other task or reading project I simply HAD to complete first.
But, because I had SO enjoyed the first 2 books in the series and even the writing skill in Book 3....I never could just give up on reading it. I just had to be in the right frame of mind to "tackle it".
Finally, that day arrived and I began seriously reading the storyline and soon discovered...or rather, rediscovered why I had written such glowing reviews of the first two books.
I admire Mr Ryan's skills in creating interesting and likeable characters I soon find myself rooting for and caring about their "thoroughgoing" their struggles.
The quantum physics connection gave a nice platform for the plausibility of his "solution's alert" mechanism while still giving me a nice hidey hole that all of this was just a good science fiction story."It couldn't REALLY happen." Even when the factors of human hatred and political machinations felt way too plausible in our world today.
At long last the story's dramatic tensions and plot points captured my need to answer "What happens next? Are they going to solve it in time! HOW are they going to solve it?"
That's when Mr Ryan's writing skills once again captured my involvement and made me glad I'd kept reading.
I even started getting excited by the email alert that says Book 5 will soon be released. I'll be interested to see where he takes us, his loyal readers now, next!
Meghan Top Amazon Reviewer - Brilliantly written! JC Ryan's new book, 'The Sword of Cyrus',is as deeply riveting as his previous three thrillers--although having read("devoured" is perhaps the better term) the author's previous books, I get the strong sense that the Rossler Foundation Series just keeps getting better and better. And here I speak as someone who does not make unnecessary high praise lightly. JC Ryan's latest book is astonishingly well-crafted, the layers of meaning cleverly interwoven and meticulously built up so that by the time you're reading the last few chapters, it all feels as satisfying as a desperate embrace.
In 'The Sword of Cyrus', author JC Ryan quite cleverly stabs a finger into the open wound of the old tension between the US and Iran.However, Ryan ups the ante--and in quite a breath-taking literary fashion at that--by making the threat real and palpable--especially when you have a determined villain who takes his cues from Biblical prophecies. Especially when you have a villain who is in possession of the world's most powerful, hitherto unimagined weapon: a bomb so small and portable yet so powerful that it can level multiple cities and annihilate countless millions. The target? The American heartland.Now, it is up to the men and women of the Rossler Foundation to counter the threat. If they fail, the consequence is unimaginable.
It is worth noting that, like any other good book, the plot of 'The Sword of Cyrus' is driven by an emotional gravity that anyone can relate with. Sure, Dalir Jahandar maybe someone you can easily hate or fear,given the current world events and the rampaging onslaught of a group like the ISIS. But Dalir is also coming from a place of incredible loss, and his thirst for revenge--which makes him blind to everything else and sets his path on fire--is utterly believable. On the other hand, the Rosslers are awesome, yet vulnerable in certain aspects. And it is this vulnerability that makes Ryan's books such a joy to follow and inhabit--these novels literally leave you clutching the edge of your seat.
This is the fourth book in the acclaimed Rossler Foundation Series. And these are full-length novels, not one of those "novellas" others keep on churning for the sake of a quick buck. The quality--and the delicious length--of Ryan's books always make any book he releases such an enjoyable literary treat. And yes, although this is the fourth book in the series, it can stand on its own--you get a good sense of what the Rossler Foundation is,anyway, and what its agents do. But then again, as a highly recommended modus,I suggest you pick up a copy of the previous books ('The Tenth Cycle', 'Ninth Cycle Antarctica' and 'Genetic Bullets'). In any case, you'll meet familiar characters (the Rosslers, of course), and a few new intriguing additions that add a deeper dimension to the story.
Most importantly, I have said this before and I'm saying it again: JC Ryan is a literary alchemist: he has the knack for crafting a blend of archaeological facts and scientific knowledge and transforming them into literary gold. There is not a page wasted in 'The Sword of Cyrus'--every moment as tight and gripping as the next one. Read even the first few pages of 'The Sword of Cyrus' and you'll see what I mean.
Get a copy. Techno-thriller fans who actually love well-written suspense books that will take you on an unforgettable ride--you will love this book.
Definitely a five-star novel.

- Reviewed in the United States on February 16, 2016Okay, here we are at the fourth installment of "The Rossler Foundation" series. The plot involves how the Rosslerites handle having unleashed an ancient virus that, because of genetics, only kills most people of Semitic ancestry. It is due to an old bit of "junk" DNA. Even though they created the vaccination and cure, certain Muslim Jihadists decide that the time has come for them to take over the world. One cleric, well, actually two, declares himself the prophesied "Twelve Imam." One of them dies from the virus so we are left with the worst of them. While I found myself intrigued and enjoying the way the story unfolded and the way certain characters developed, I found this to be a bit of a predictable story. If you have read the previous three books in the series, you are likely to enjoy this one. One aspect of the story is after the Rosslerites realize what a threat the ancient order of behind the scenes manipulators, the Orion Society, is, they dispatch all of its members in a rather quick and somewhat hard to believe manner. After all, they have been manipulating world events from behind the scenes, anonymously, for a very long time. Yet the Rosslerites, with the help of law enforcement around the world, eliminate them. Odd.
Anyhow, this is a decent read and if you are caught up in the series, this will come as a nice continuance of the story arc.
- Reviewed in the United States on October 27, 2014What a stunning addition to the Rossler Foundation books! I did not think I could possibly be more riveted and engrossed than I was while reading the previous books, but The Sword of Cyrus has impressed me once again. This book was so well-written and perfectly executed that it’s difficult to capture everything I feel in one measly little review. From cover to cover I was unable to put the book down; I was locked for hours within the intriguing pages of this action-packed and suspenseful technothriller.
JC Ryan has a real talent for capturing the reality of the horror and the tension of every plot twist, making you feel like you’re right there with the characters; their struggles are your struggles. I feel like it must have taken a TON of research and hard work to develop this book as expertly as the author has done. The exploration of political conflict and religion fanaticism are masterfully written. What really hooked me were the characters. Every one of them was so real to me, and I was deeply invested in the conflict.
Overall, this was a fantastic reading experience, and I would love to see these stories on the big screen someday. I did like the chapter titles in the previous book a bit more, because I felt they were more lighthearted and humorous, but these ones were more serious. I felt like this book had a much darker vibe, which was part of what made it so captivating. I highly recommend this to anyone who enjoys any sort of truly intense mystery, thriller, or suspense.
- Reviewed in the United States on May 1, 2015I found this book to be quite interesting in that it continues well with the rest of the series written so far and JC Ryan's writing seems to be improving, even though it was very good to begin with.
I enjoyed the story line for being plausible and in keeping with the entire series train of thought. I found only one minor detail incorrect out of the entire book, not the theory or mechanics which I do not have the background to challenge, but with a comment in the book. There may have been others that I did not catch but that is for others to find.
The characters continue in their development through the series with new characters being introduced.
The plot was reasonably acceptable if the book was a stand alone but melded well with the previous books.
I really can't say that there is anything that stands out which I did not enjoy about the book.

5.0 out of 5 stars The fourth in the series and just as good as the first one written
The fourth in the series and just as good as the first one written. I couldn't put it down and was captivated by the theories of previous advanced civilisations on this plant which has been around for four and a half billion years. It is entirely conceivable that there were other people before us and that we are their descendants.
Have our ancestors been thrown into such chaos by the disruption of some world catastrophe that they lost the memory of their own past? It is very likely and not remembering it means we have no known link to our previous distant ancestors even though they no doubt existed.
JC Ryan takes this on board and with great skill introduces us to a remarkable and pleasant group of people who delve into the mysteries and come up with some pretty convincing theories.
Read The Tenth Cycle first, then The Ninth Cycle before going on to Genetic Bullets and finally The Sword of Cyrus.
JC Ryan takes today's stresses in hand and delivers some very compelling thoughts on the subject.
