Stranded in India without documents, Aisha is interrogated by RAW, India’s intelligence agency, and the FBI – both of whom seem to know more about her husband’s disappearance than she does.

At the same time Adam’s ex-lover, Sara, receives an urgent message from him: ‘Help her’.

Thrown together by circumstance and suspicion, Aisha and Sara decode Adam’s clues, which lead them across the US in a hunt to find Adam before it’s too late.

Rated 5 out of 5

Ajay Chowdhury’s Eden Falls is a gripping, emotionally rich thriller that begins with a moment of pure shock and unravels into a global mystery full of tension, betrayal, and the frightening power of technology. It’s the kind of novel that pulls you in instantly and keeps tightening its hold with every chapter.

The story opens in Delhi, where newlyweds Adam and Aisha are preparing to fly home from their honeymoon. In a heartbeat, everything collapses. Adam disappears in the chaos of the airport, leaving Aisha stranded, terrified, and holding onto a single, devastating message: I’m sorry. Chowdhury captures the panic and heartbreak of that moment with cinematic clarity, placing you right beside Aisha as her world fractures.

What follows is a relentless unraveling of secrets. As Aisha is questioned by both the FBI and India’s intelligence agency, it becomes chillingly clear that they know far more about Adam than she ever did. The emotional weight of that realisation is handled with real sensitivity Ajay Chowdhury shows how love can blind us, how trust can be both a comfort and a trap.

Meanwhile, thousands of miles away, Sara Wolf a brilliant but sidelined scientist at Princeton receives a message from Adam she never expected: Help her. Sara’s re‑entry into Adam’s life, and her collision with Aisha, is where the novel truly ignites. Their uneasy partnership is the emotional core of the story: two women bound by love, suspicion, and a man full of secrets, forced to rely on each other as they chase the truth across the United States.

Chowdhury excels at blending character depth with high‑stakes plotting. The world he builds — weaponised AI, billionaire tech moguls, hidden research labs feels frighteningly plausible. The pacing is sharp, the tension constant, and the twists land with real force. Yet beneath the global scale and technological intrigue, the novel never loses sight of its human heart.

Eden Falls is smart, modern, and utterly absorbing — a thriller with pace, emotion, and a pulse that never slows. Chowdhury proves once again why he is one of the most exciting voices in contemporary crime and thriller fiction.

A bold, cinematic, and deeply compelling read.

Wow! This is a brilliant book. I’m not a big fan of thrillers but this really got me going. The writing is excellent and the plot has just enough twists to keep me interested but not bamboozled. The plot concerns, well it’s quite difficult to describe, but it is about AI, alien intelligence, and its main villain who wants to dominate the world. There’s a chase of the two main female characters, Sara and Aisha, by the FBI, the villain’s henchmen and Indian secret service agents. Exciting.

I have read Ajay Chowdhury before, his detective novels and really enjoyed them. This is a bit of a departure for him and I was surprised to enjoy it so much; if I write much more I will begin to give plot spoilers. Just give it a go I think you’ll enjoy it.

An object crashes to earth in the New Mexico desert. Is it a meteor? Time will tell.

Delhi airport. Newlyweds Doctor Adam Stone, a Nobel prize winner, and Aisha Ali cut short their honeymoon following the unexpected death of Adam’s best friend, Caleb. Adam is quiet, preoccupied, clearly troubled and just as they are about to board their flight back to the United States, Adam decides to go to the duty-free and disappears. He leaves Ayisha stranded with no boarding card and more importantly, no passport. Before he disappears, he’s able to send two messages, one to Aisha which says ‘I’m sorry’ and one to scientist Sara Wolfe, his ex, which says ‘Help Her’.

During questioning by India’s intelligence agency and later the FBI, it becomes clear they know far more about Adam than Aisha does. Despite her reservations, Ayisha realises she must work with Sara in order to seek the truth of where Adam is, and why he has disappeared…

This is so completely different from the authors excellent Kamil Rahman series, though he does get a brief mention! It’s a really believable, dystopian, very intelligent, complex and 100% immersive and gripping thriller. Whilst much of the science completely passes me by, nonetheless, it adds to the authenticity and it doesn’t seem to make much difference that I’m a science buffoon as as I completely understand what’s going on! It’s very thought-provoking into the bargain it raises a lot of questions that have me deeply thinking. It presents a sort of Big Brother future that gives me chills. Indeed, some of the technology that is mentioned here is already well under way. We have a Tech billionaire whose power is beyond scary and whose vision for the future is a warning to us all not to go blindly in. I wonder who he’s based on??!

It’s a fast flowing plot set in some vividly described, amazing locations that are creatively used in some very dangerous, movie worthy scenes. It’s suspenseful, tense, full of twists and turns with some surreal scenes that contrast sharply with the scariness and fear.

Whilst obviously there’s a sci-fi thriller element to the book, this is balanced with a very human and moral element too, as Adam tries to figure out the quest for research with his love for Aisha and his care of Sara and what’s best for the future. Whilst much of this is speculative there’s also a great deal here that is all too plausible.

Overall, I enjoy this ‘chase’ very much. It’s undoubtedly well written, full of thrills, the characterisation is excellent, it’s intelligent and makes me think. What’s not to like?

I’ve never read a book by this author before but after this I would certainly read more.

It was a fast paced, race against time thriller which reminded me a little of the Da Vinci code with the 2 main characters having to solve clues to find what they were looking for. An enjoyable read.

Swapping the London streets for the desert of New Mexico this latest from Chowdhury announces itself straightaway with a bang. Is it or is it not a falling meteorite? The conclusion officially is that it was a hoax played by a group of students. But what was it? The suspense is created early on and what is found within the meteorite is only partially explained. This is speculative fiction.

Switch to a crowded scene in India several months later. (Nobel prize winner, Astrophysicist) Adam Stone and Dr Aisha Ali (Associate Professor, her English Literature PhD was based on James Joyce’s Ulysses) are being driven (slowly) to the airport. They have had to cut their honeymoon short because one of Adam’s closest friends has died. Arriving in time Adam wants to go to the duty free area and that’s the last Aisha sees of him. She can no longer travel as Adam has her passport. She is baffled by Adam’s last message and seeing him on CCTV taken away by some apparent security people. The Indian intelligence service are now involved. But why?

We are in the world of tech billionaires – enter the archetypical and arrogant Markus Noel, driverless cars and AI implants. Noel’s AI device called Manx appears to be an advanced version of Siri or Alexa and has made him his billions. Those who wear them are known colloquially as Mankies. Aisha wears Manx smart spex an advanced communications device, it creates efficiencies like answering standard emails and produces background information in moments. She is also beta testing an embedded implant which regulates her medication for severe migraines to the extent she appears she is becoming more and more reliant.

Markus Noel is behind Adam’s kidnap and wants the Prometheus device which Caleb his friend stole at Adam’s request. This will be the best technology ever. It could end poverty and hunger or be used to create the biggest weapon of all time. Noel’s agents failed to get the information from Caleb who after a beating died of a heart attack. Noel also has the ear of the President (who is described as unstable). An Indian emigre was also working on the initial project but sidelined and is now prepared to sell to Indian intelligence for a price. Aisha has contacted the FBI and so they are now also on the trail.

Before Adam was taken he sent a message to an ex-girlfriend asking her to contact his wife and his last message to Aisha was simply ‘I’m sorry’ so when Sara turns up Aisha is rightly suspicious. They don’t know what they’re looking for but finding Prometheus will help them find Adam. They have to crack the hidden code from a series of numbers and then locate the three parts of Prometheus hidden by Caleb.

Spoiler.
Part 2 returns back to the beginning. To the beginning of Aisha and Adam’s relationship and the meteorite story.

It’s a thriller and there are plenty of people following Aisha and Sara so chase scenes galore. They might evade one lot of people after them if they ditch any tech they have but this might not do the trick for another interested party.

No one who wants the Prometheus restored appears to have humanity’s salvation as their goal. So who will succeed? Will Adam be saved? What will happen to his relationship with Aisha?

A roller coaster of a thriller ride. Although Markus Noel is an archetypical villain the two main women characters, Sara Wolf and Aisha Ali are believable, intelligent and brave. They are neither villainous women nor ultra-feminine women who need male protection.

Four stars. Recommended to science fiction and thriller readers alike.

Having enjoyed several of Ajay Chowdhury’s books in the past I was surprised to find that this story did not initially appear to follow the characters from the writer’s previous novels, But this doesn’t matter as we are quickly lead into a precarious situation where a newly wed’s husband goes missing, shopping in an airport duty free area and one of the biggest problems if not that, it’s that he holds his wife’s passport which means she cannot board the flight alone or with him which means she needs embassy help very quickly. As a reader, it may take some time, but you are going to learn a lot about Adam’s past and it is clear that his new wife knows almost nothing of his real past. Adam does leave a series of clues and this is where you will find the involvement of AI becomes a virtual lead in this story and it’s perhaps a prediction of what might happen in the very near future. The power of AI becomes a major force in this novel and it’s more about can it be controlled rather than who is controlling it. This is an excellent read, but I still hope the writer goes back to his previous characters at some stage. However this was an excellent digression and I look forward to the next by this writer as they help you to think and read quickly with the situations explained.

This is a gripping, intelligent thriller that pulled me in almost immediately. What begins with a shocking murder and the sudden disappearance of a newlywed husband quickly unfolds into a much larger and more complex mystery. As the search for the truth deepens, two women connected to the same man are forced into an uneasy alliance, uncovering secrets that stretch far beyond their personal lives.

What I particularly enjoyed was how character-driven the novel is. Beneath the high-stakes plot are deeply human threads of lost love, a struggling marriage and the complicated loyalties that bind people together. I found myself genuinely caring about the characters and their determination to uncover the truth.

The story also explores the growing power of artificial intelligence and its potential impact on humanity, alongside the mystery of a meteorite discovery, giving the novel a fascinating speculative edge that feels unsettlingly plausible.

Tightly paced, thought-provoking and emotionally engaging, Eden Falls is an intricate thriller with real heart. A compelling and memorable read, an easy five stars.

I was lucky enough to receive an ARC of Eden Falls through NetGalley and the publisher, and wow – this is one of the best speculative thrillers I’ve read in a long time.

From the very beginning, the suspense had me completely hooked. I loved trying to work out the codes alongside the characters, all while feeling that constant tension of wondering whether they’d get caught. It made for such an immersive reading experience, and I found myself racing through the pages.

I was especially rooting for the two female protagonists, whose determination, intelligence, and resilience made them impossible not to cheer on. Their journeys added so much heart to an already gripping story.

Ajay Chowdhury has written a fast-paced, thought-provoking thriller that feels frighteningly plausible. In a world where AI is advancing at an incredible rate, Eden Falls explores ideas that are both fascinating and unsettling, making it feel like the kind of story that could one day become reality.

A brilliantly written, intelligent thriller that perfectly balances action, suspense, and timely themes. I couldn’t put it down and highly recommend it to anyone who enjoys speculative fiction with a chilling edge. ⭐⭐⭐⭐⭐
