Nexus Dei marks the inaugural installment in Judah Lamb's latest series, The Eden Protocols. This narrative revolves around a man and his family as they endeavor to comprehend the essence of humanity. Their exploration unfolds during dinner conversations centered on scientific topics. Elias's children often strive to surpass their father's insights during these discussions, occasionally succeeding.

The family embarks on a vacation, which leads to an unfortunate accident. Upon awakening from a two-year coma, Elias finds himself uncertain whether his family is composed of humans or artificial intelligence. He grapples with the reality of his current existence—whether it is genuine or merely a figment of his imagination. If his family is indeed not real, what has become of them? Are they still alive? What transpired?

From the very first page, Nexus Dei held me in a state of suspense. The conversations between Elias and his family provided ample food for thought. I found it difficult to cease reading, as the information presented was exceedingly captivating. I was eager to discover the outcomes of Elias's experiments.

Ever had the feeling of discomfort with what your reading because it hits to close to home, it certainly is the case with this novel. Seeing the way we are slowly becoming more dependent on AI, computers, phones is disconcerting. Leaving the real world behind for something that is easier. I absolutely believe this novel is where the world is heading (not exactly but you get the point)

There is a main theme of catholosim in the book, but I truly enjoyed the way the author made me realise how important it is to stay connected with the world around us and to be the people we were created to be.

Oh also major cliff hanger 🫣.

Elias awakens after being involved in an accident and is told he has been in a coma for 2 years. When he enquires about his family, he is told his wife Serafina and his 2 children Mateo and Anais are well and looking forward to seeing him. He is allowed to go home, but is very weak, his muscles have wasted whilst lying in a coma. When he finally gets to see his family he cant believe the changes in them all, especially his children. Anais is totally different in her attitude and her appearance, gone is her brightly coloured hair.
Elias starts to go outside for walks with Serafina and neighbours suddenly appear wishing him well and exchanging pleasantries with him. Which he finds very strange as they didnt used to. He starts to find things are so perfect, including his family, that he begins to doubt everything.
Then a priest tells him he is not living in the real world but one created by AI and that his family are not real people but AI generated to keep him happy. The real world has been devastated by a nuclear war. If these things are true, then is his real family still alive and if so where are they.
The priest reappears and tells him he can help him escape the AI world, but it will be dangerous, especially as he has been "connected" to the AI interface for over 2 years. But he is determined to get out of this AI generated world and back to the real world to find his wife and children, even if it kills him trying.
Never a religious man, he now finds that he is praying to God for help and prayers from his childhood are coming back to him.

I apologize for the delay in submitting my review. The past year and a half has been particularly challenging due to my experience with a brain tumor, and I continue to face both physical and cognitive aftereffects. A recent setback necessitated a week-long hospitalization, which further contributed to the postponement of my review.

This is not the first book I have read by this author, who has quickly become one of my favorites. Nexus Dei marks the inaugural installment in Judah Lamb's latest series, The Eden Protocols. The narrative follows a man and his family as they seek to understand the essence of humanity, exploring this theme through dinner conversations that center on scientific topics. Elias's children often strive to surpass their father's insights during these discussions, occasionally succeeding.

From the very first page, Nexus Dei captivated me with its suspenseful narrative. The dialogues between Elias and his family offered ample intellectual stimulation, making it difficult to put the book down. The information presented was exceptionally engaging, and I was eager to discover the outcomes of Elias's experiments. The text is enriched with valuable life lessons interwoven with themes of faith. I particularly appreciated the author's notes at the end.

I received an advance review copy at no cost, and I am leaving this review voluntarily.

This is an amazing first book in a new series and it is so relevant to our times it terrified me. This is the story of Elias who is a brilliant scientist carrying out research to further the AI world. He seems to be reaching a breakthrough when he meets a new Korean student who is even more brilliant than him. However when they work on the breakthrough all hell is let loose. Elias is married to a catholic woman Serafina, who has great faith and puts God before science but Elias is a true agnostic. An accident happens and when Elias comes out of his coma he is told he has been unconscious for two years, and when released from hospital he notices how different the world had become. But everything was so picture perfect he started questioning, and being the great scientist that he was he started to figure out he was living a lie.The scary bit is that maybe we are all already living in a simulated reality, that the AI we have created are already becoming more powerful and more intelligent than us, and we are all risking losing our humanity. It's funny how one is depicted as turning to God when fearing their death, however, I love were this series is going and cannot wait to go on reading

Apparently I'm on a sci-fi suspense kick, and Nexus Dei is exactly the kind of book that justifies it.This is equal parts captivating and unsettling.

The premise alone hooked me: a man wakes up to a perfect world and slowly realizes it's a lie. What follows is a gripping, thought-provoking thriller that doesn't just entertain — it makes you genuinely reflect on where technology is taking us and what that future might actually look like. It felt startlingly realistic, which made it all the more compelling.

For a Matrix-style dystopian thriller that also carries real theological weight, this one is hard to beat. Super enjoyable, deeply captivating, and the kind of story that sticks with you.

This has got to be my favorite series so far by this author. It kinda feels real. Like it could happen. In my opinion it examines why we should look into the ethical ramifications of our choices. Good life lessons woven into faith lessons. Love this authors notes in the end.

Clean, dystopian, AI, tech, loss family, faith.

What does it mean to be human? Is perfection really what we seek?

These questions are addressed well in this start to a series set in a post-apocalyptic, AI-saturated world. I look forward to the continuation of this series.

PS - Don't ask the book's AI! Read the book for yourself; it will be worth the time.

Elias has been in a coma finally waking two years later. Everything is perfect on the surface it seems. Yet things are not as they seem. This is a chilling look at reality with AI. Terrifyingly true representation of what can happen if things are left to grow and let to continue. God help us.

"Nexus Dei" is a gripping story about the clash between artificial intelligence and humanity. Set in a future where simulations dominate, humanity struggles to reclaim its place on Earth. With excellent world-building and nonstop action, it’s both an entertaining and thought-provoking read.

Nexus Dei Book 1 of The Eden Protocols by Judah Lamb is amazing start to a new series. It's like if the Matrix and The Legend had a baby, a weird and fascinating world that sucked me in and wouldn't let go. I'm waiting for the next book...not so patiently.

Wow. There are a lot of discussions about the possible consequences of AI. This author made those discussions relevant, socially and spiritually, in this novel. Just reading this stretched both my mind and my faith. I am definitely reading book 2 when it becomes available.

I received an ARC from the author and I am voluntarily leaving a review.
