Nexus: A Science-Fiction Thriller

by Douglas E. Richards, Joshua T. Calvert

Three impossible objects with the mass of neutron stars are hurtling toward Earth. Will they shatter reality as we know it? Or crush humanity to dust?

Multimillion-copy bestselling authors Douglas E. Richards and Joshua T. Calvert deliver a mind-bending near-future thriller that fuses cutting-edge physics with the deepest secrets of ancient Egypt.

When physicist Lukas Heuer discovers three anomalous pyramid-shaped objects in deep space, hurtling toward Earth, he knows humanity’s days are numbered. Because the objects are so massive, if he and a small group of scientists can’t unravel their purpose and origin, their gravitational pull will tear Earth to rubble—before they even get close.

Half a world away, archaeologist Mira Najafi discovers a hidden passage in the Great Pyramid containing an ancient drawing of three black pyramids against a blue sky—a clue her vanished father left for her fifteen years ago, the last trace of the man she never stopped searching for.

Two seemingly unrelated discoveries. One impossible convergence.

As Lukas and Mira race toward the same cosmic nexus, they uncover a presence that has been watching humanity for millennia—a presence now awakening in our solar system. Because these physics-defying objects aren’t just arriving.

They’re returning.

What follows is a desperate mission to the edge of human a journey that will force a handful of scientists and explorers to confront the limits of physics, consciousness, and reality itself.

Because the pyramids aren’t just objects. They’re keys—and the door they open may change humanity forever . . . or erase it entirely.

Nexus is a high-concept, high-stakes thriller that will leave you questioning the nature of reality, and what it really means to be awake.

[Maria Fledgling Author Park · Rating 5 out of 5]

Do you live in Flatland?

Nexus is billed as a Science Fiction Thriller. It is multiple levels deeper than just that one topic. As often as I read Douglas E. Richards' books, I should know that his exceptional talent lies in layering thriller plots with subplots of substance and weaving a path through science, physics, mathematics, philosophy, mythology, and spirituality that makes complete sense.

Nexus is a capital-T thriller, capturing the reader in the first chapter and holding them in delicious suspense until the final page. With each new element he introduces, the tension is ratcheted up. The characters even manage to do 8 billion dollars' worth of damage to Switzerland's CERN, the Large Hadron Collider.

Nexus centers around two main groups of people; advanced physics and astronomy scientists, and archaeologists who specialize in Egyptology. Add in boatloads of bureaucrats, paddle boats of politicians, and go-karts of government officials and you have a good idea of the chaos of part of the plot.

The story revolves around the Great Pyramids of Giza, and 3 spacecraft that turn out to look exactly like the Pyramids. In the process of trying to find a way in which to communicate with the incoming crafts, our scientists and Egyptologists go on a mind-blowing journey.

Nexus is by far one of my favorite Douglas E. Richards books. My myriad of reading interests are all packed into one fabulous book. What's not to like? I highly recommend it, and hope you will buy a copy and see for yourself.

I despise alien stories around the pyramids or other ancient discoveries, they just don't sit well with me. So it's a testament to how much I like Doug's work that I picked this up in the first place.

I enjoyed it to a degree, although it was missing a surprising number of Doug's tropes and the reverence for the US president, although not holy new, stuck in my craw given the current incumbent. That's nothing I can blame the authors for, of course. I quite liked the characters for the most part, although the relationship between Heuer and Mendoza felt thrown in my face and there were a few minor editing tweaks that made this one feel not as tight as some of Doug's others.

As always, I liked the authors note at the end. So even if this particular twist on the genre didn't overly appeal, I enjoyed the story for what it was.

[Deborah Zaranti · Rating 5 out of 5]

Amazing story!

As always there is so much science FACT contained in this story! I've recently been studying consciousness from people who have had awakenings about the true reality of the larger consciousness we all exist as a part of. Doug and Joshua definitely did their homework. Everything they've written agrees with the theories and teachings of both Thomas Campbell (My Big TOE - Theory Of Everything) and Sydney Banks (The 3 Principles).

IRL, Humanity is finally beginning to evolve to the point where we are ready to take the next step in understanding the truth of our lived reality. Hopefully this book will be read by millions of people. Even if this story only opens a few hundred minds to the possibilities of what Humanity can attain, that will be a great start.

Thanks to Doug and Joshua for your part in helping further our understanding of the possibilities that exist for us all.

This isn't a review, just me again notifying my followers that Nexus is now available on Amazon! This is my latest hard science-fiction novel, written in collaboration with Joshua T. Calvert. And while my recent books have gotten away from hard science fiction, this one is a return to my roots that I think you'll really enjoy. Nexus is a wild ride. Accurate and mind-blowing, with concepts you'll be pondering long after you've finished the novel.

Here are the first few paragraphs of the synopsis.

Three impossible objects with the mass of neutron stars are hurtling toward Earth. Will they shatter reality as we know it? Or crush humanity to dust?

Multimillion-copy bestselling authors Douglas E. Richards and Joshua T. Calvert deliver a mind-bending near-future thriller that fuses cutting-edge physics with the deepest secrets of ancient Egypt.

Much better than I thought it would be!

This is a great read and kept me turning pages at an amazing rate! I am a slow reader by choice, but this book had me reading for long periods of time, because it was so gripping. The characters were very real and complex and it was very easy to put myself in their shoes! I am an avid reader and usually have my nose stuck in a book. I prefer actual books, but use my Kindle often, when I can't find anything locally that seems promising. DR and JC really did a great job making this a worthwhile read and I will looking for more of their works, both individually and as a team! Hope you enjoy this as much as I did!! Thanks, guys! Doug.

[Alvin Narsey · Rating 4 out of 5]

well u know... because the study of Dzogchen is insight into the nature of consciousness and quantum stuff... loved the cross link with ancient Egypt.
expertly written.
will try another from either of these boys.


3 mysterious pyramid-shaped objects heading toward Earth from deep space

Two parallel storylines — a physicist (Lukas) tracking the objects, an archaeologist (Mira) decoding ancient Egyptian clues

Hidden Great Pyramid passage contains ancient drawings of the same three pyramids — they've been here before

Physics + consciousness + Egypt all tied together — the pyramids are "keys" linked to human awareness

Endgame: activate them = either next-level human evolution or total extinction

A mind blowing tour de force!

Nexus is an absolutely mind boggling sci-fi thriller of the highest caliber, the kind of book that never leaves you, like Blasphemy by Douglas Preston. You might just find yourself suddenly interested in meditation, A net win for everyone who reads Nexus, too. The plot involves the appearance of 3 impossible objects near the orbit of Mars and the attempts by all of humanity to stop them from destroying Earth. The plot is fast paced, the writing exemplary and characters are all brilliantly composed. Overall, 5/5 stars, highly recommended for fans of sci-fi, thrillers and anyone interested in the nature of reality itself!

[Michael Henderson · Rating 5 out of 5]

Everything explained, simply, profoundly.

Nexus is a profound possibility. I as an astronomy student struggled with many of the concepts that the authors present simply and profoundly. Dark matter, dark energy, black holes. The problems with the universe all seem relatively simple in this novel.

But what if the authors are correct? What if there are multi-dimensions beyond our simple concepts of four dimensions? What if, Einstein is just the beginning?

I truly enjoyed reading this book. The first science fiction book that really captured my attention since The Foundation Trilogy by Asimov.

Thought Provoking Read

This Is the 1st book I have read By Douglas Richards. As a physician with an undergraduate majored in quantum chemistry' who is fascinated by the "hard problem of consciousness"; as well as someone who meditates daily, I found this book absolutely fascinating. It is a thriller but at the same time thought provoking and filled with cutting edge science. For anyone who shares these interests, I strongly recommend this book. I will certainly read more books by Douglas Richards.

[Timothy R. · Rating 5 out of 5]

Excellent read

I've read all of Doug's books and have thoroughly enjoyed "most" of them. This one may not have been one of my top favorites but it certainly kept my attention throughout. I normally read whole working out on an elliptical and can always tell if the book is good or not by how often I have to check the clock! This book made the time fly by.
In addition I love reading Doug's explanations at the end of the books. Plus if you email him he will reply to you.

[Shawn · Rating 1 out of 5]

As so often happens these days, this is science fiction for people who don't give a damn about science. I confess that I began skimming each page after the Tibet chapter, but I did finish it and certainly got a good grasp of the ideas and arguments. If you believe that ancient Egyptians were insufficiently advanced to have built the pyramids without the aid of extraterrestrial 11-dimensional beings, this is the book for you!

[Lee-sa Day · Rating 5 out of 5]

Fascinating book

My stepfather is from Thailand and I have been to numerous temples in our area and found the information in this book fascinating. I have always been fascinated by Egypt and of course the Pyramids. The book was not a quick read as you want read and then let everything you read cycle through your mind a few times. I believe it would be literally impossible for a bad book to be written or con written by my favorite author, "Douglas E. Richards.

[Lindan A. · Rating 5 out of 5]

a good collaboration between the authors

I was previously turned off by Richard inserting his right wing views in a previous book. But there is none of that distraction in this book. Sadly for me, since watching the Age of Disclosure documentary my thoughts on first contact have changed, but there is room to dream of second contact. Or in the case of this book, a scenario with other possibilities.

[Ronald Barrett · Rating 3 out of 5]

I usually like sci-fi that is heavy on the sci part but I prefer it to be integrated into the story. In Nexus too often the characters are "lecturing" other characters in the story. It felt more like an insertion of current theory rather than a smooth transition. Several times the lecture was repeated, in whole or in part, but to different characters. The story itself was interesting even in spite of the sometimes clumsy presentation.

[Christine Soldwisch · Rating 5 out of 5]

Mind-blown!

Wish I knew physics, but maybe glad I dont! Too many bad habits to break to understand a new reality. When I wasn't confused, I rather liked glimpsing into deep meditation. You have to read it to understand, but then of course, you won't. Still, you might be left with a feeling of gentle joy.

[Jim · Rating 5 out of 5]

Excellent, totally enthralling & very inspirational.

This book surprised and delighted me from beginning to end. It embodied so many of the deepest thoughts and beliefs that underlie our current understanding of life, consciousness and our very existence. I highly recommend it to anyone who wants to venture down and explore these avenues.

[Robert Siegel · Rating 5 out of 5]

Spectacular

I couldn’t put this down. Exciting. Believable. Very well written. Richards and Calvert present an incredible problem threatening the world and tie multiple sciences together in an exciting and highly readable adventure. Give me ten more novels like Nexus! (And I won’t move off my couch for ten days).

[Farhan · Rating 5 out of 5]

4.5/5.. classic Sci Fi read. Very enjoyable and full of real-world science. Reminded me a bit of Interstellar.. Science fiction based on solid science. Loved the concept of a multi-dimensional eternal being, contacting humans to make them realize they need to raise themselves higher than the mundane three-dimensional world they live in.

[Elizabeth Bartley · Rating 5 out of 5]

Mindmeld. Who knew?

I'm a fan of Sci-fi and Archaeology, especially Ancient Egypt, so I picked this book to read with more than a little excitement. It did not disappoint, I could barely put it down. Star Trek got a couple of funny mentions, I especially giggled at the Tibetan Monk, referring to it! No spoilers, read it yourself

[S.E. Foulk · Rating 5 out of 5]

Very different...

I don't usually get a metaphysical message from the sci-fi books I read, but this was very different, and quite mind expanding. Considering the age we are entering, this story is an excellent warm up for what lies ahead. The mystery solved will blow your mind. Enjoy.

[Francine · Rating 5 out of 5]

Nexus was mind-expanding & thoroughly enjoyable!

This book led me to discover so many amazing things that I could not have imagined to actually exist, all while weaving a massive story of profound implications. I love books that invoke further thought about life and its mysteries. I highly recommend this book!

[Robert Smith · Rating 5 out of 5]

Great book

I truly could not put this book down. I think I read it in four days. Such mind blowing concepts about the human mind. If something like this happened it would change mankind future overnight. I recommend reading this to all that love science fiction.

[Tommy · Rating 5 out of 5]

This is an action story that goes deep into consciousness and existence but is explained and they make it all work. His books are so well thought out I cannot image the amount of research done and they tie it all into a good story - Amazing.

Wow and more Wows

Nexus is about the 'Next Us' and becoming that is the start of our collective Eureka. Thank you Douglas and Joshua for creating a narrative that gives us ALL the breadth of new life. GaryG

Brain Food

I am intrigued with new concepts of consciousness and communication through quantum entanglement and watching science and religion meld and turning it into an Indiana Jones meets space was entertaining.

[Michael · Rating 5 out of 5]

Gripping!

Two seemingly disparate events, one in the Egyptian desert, one in deep space, converge in importance in this story. The authors take the reader on a thought provoking journey that will make you anxious to see what happens next.

Well done! Great read!

Gripping Tale

Is consciousness reality...did it come before material objects? These and other fascinating questions are posed in a well written and compelling story of mysterious " pyramids".

[Marlene M. Oaks · Rating 5 out of 5]

P Phenomenal metaphysics

This book combines physics, metaphysics, and every branch of science with all of the speculations of science fiction, and a fascinating and exciting story. What a recipe for a good read. I recommend you take this journey.

[Claire Sadowniczak · Rating 5 out of 5]

Reminscent of Arthur C Clarke

Hard science fiction reminiscent of the novels of Arthur C Clarke. Great theories on how the human brain works and how consciousness affects reality visa vie quantum mechanics but in layman's terms using easy to understand examples

[Mark Valan · Rating 5 out of 5]

Tired of reading the SAME OLD STUFF?

Try this one! Thought provoking and engaging. I enjoyed this thriller about the power of the mind. Couldn't put it down and I actually learned a lot!
