Fault Lines
The production wrapped early. The body count didn't.
In Mexico City, loyalty is currency, trust a liability, and some secrets are worth killing for.
"If you loved The Year of Living Dangerously, this belongs on your shelf. Same outsider-in-chaos energy—but with film producers instead of journalists, and emotional stakes that cut deeper."
He came to make a film. He might not live to finish it.
When an 8.0-magnitude quake tears through Mexico City in 1985, it doesn't just destroy buildings—it exposes the fractures running through one of the world's most powerful crime families.
Mark Sinclair thought he'd escaped the soul-crushing world of advertising when he arrived in Mexico City as associate producer on a $12 million NBC miniseries starring Burt Lancaster. But in a city where loyalty is currency and trust can get you killed, his Hollywood dream becomes a descent into Mexico's criminal underworld.
Enter Marta Salgado—brilliant, beautiful, and dangerously connected. She solves Mark's impossible production problems with a few quiet phone calls. As their professional relationship turns personal, Mark learns the Marta's family doesn't just have connections—they are the connection between Mexican cartels and American intelligence, between government officials and the bodies that vanish at night.
When Marta steals documents exposing decades of blood money—from the 1968 student massacre to CIA-funded arms deals—she and Mark become targets of both her brother's cartel enforcers and their own production's betrayals. With the city in ruins and nowhere left to run, they must navigate the fault lines of a collapsing conspiracy that stretches from Mexico City to Washington.
"Smart, sexy, tense. I'm obsessed."
"Fault Lines is what Lee Child would write if he cared about psychology—fast, grounded, and unexpectedly moving."
This is a story where the quake that levels a city is nothing compared to the aftershocks that follow—where love isn't about perfection, but about finding someone worth the wreckage.
The quake stopped. The manhunt started.

About the author
Jeff Nelson
2 books11 followersI'm Jeff Nelson, a television producer, documentary filmmaker, and novelist whose novels explore love inside worlds designed to prevent it—old-money estates, family dynasties, closed systems where the rules protect the powerful and quietly decide who gets in.
The Montecito Rules draws on my intimate knowledge of California's coastal elite. I spent formative time on my great-aunt's 72-acre Montecito estate—complete with staff, tennis courts, and all the invisible rules that governed who belonged and who served. I was family, but I also witnessed the quiet hierarchies that separated those who owned such places from those who made them run. That tension—between access and belonging, between being let in and actually mattering—runs through everything I write.
My novel Fault Lines, inspired by my work producing an NBC miniseries during the 1985 Mexico City earthquake, follows a young producer who falls for the daughter of a powerful Mexican family.
Lights, Camera, Roma, forthcoming, moves the same question to Italy, where a commercial producer is drawn into the world of a film dynasty ruled by a Contessa who decides who stays and who leaves. Different surfaces, same machine: who gets to belong, and who decides.
I've also co-authored the memoir The Cuban and the Cool Kids with celebrity hairstylist Peter Lamas, and written nonfiction on subjects ranging from health to the social systems that shape human behavior. I run VegSource, a plant-based nutrition platform, with my wife Sabrina, producing documentaries and educational content focused on evidence-based health. I live in California and publish under my own imprint, Cool Key Press.

Ostensibly, a novel about an American crew making a movie in Mexico, but it’s so much more. There’s action, love, corruption, and a dangerous cartel blended into a great earthquake and its aftermath.
Very well written, like a script waiting to be filmed.

This was a good thriller overall. The first half was a bit slow but it picked up a ton in the second half and had me on the edge of my seat!

FAULT LINES
by Jeff Nelson
I’m tired … oh, so very tired. I can’t get anything worthwhile done today with this foggy brain. Why am I in this predicament? The blame belongs to Jeff Nelson. When the relaxing calls of crickets and tree frogs should have been gently leading me off to dreamland on this peaceful little farm in the middle of nowhere, instead, I was sitting in the living room with bright lights overhead, my eyes glued to the pages of Jeff Nelson’s new novel, Fault Lines.
Follow the journey of a man whose only intention was to advance his film-producing reputation by accepting an assignment as associate producer of a mini-series in Mexico. Somehow, through many twists and turns, his entire life was turned upside down.
Jeff Nelson doesn’t simply tell you what events took place; he puts you in the middle of the whole disaster. You will feel the love, pain, fear, and emotional turmoil of the characters as the situation devolves into danger, chaos, and corruption at the highest levels … on both sides of the border.
Within these pages you will be presented with thought-provoking questions that affect not only the characters involved, but your life, also. Can an average man, a simple film producer, make a real difference? Will he survive with his professional career—and, indeed, life—intact? How far is he willing to go to achieve his desires? Will he risk his entire future, and even his life, for the sake of another person?
Enjoy the journey within this intriguing book, and then get some sleep … if you can.

"Fault Lines" deftly fuses a love story, a mystery, and a thriller into one propulsive narrative. The author’s command of metaphor and personification keeps the prose lively without showboating, and the psychological portrait of the usually reticent male protagonist is a standout - his inner workings are rendered with clarity and bite.
From the arresting opening line, in which the main character lies shot, to the emotionally satisfying conclusion, the dramatic arc never wavers. The pace is unrelenting and the suspense steadily mounts; the plot is taut yet fair with its clues. As an avid mystery reader, I took real pleasure in tracking the characters’ motivations and assembling a solution that feels both surprising and inevitable.
Mexico City proves an inspired setting. Its layered history and kinetic streets provide a perfectly disorienting backdrop for the novel’s unease and paranoia. Vivid, well-chosen details bring neighborhoods and landmarks into sharp focus without slowing the story.
"Fault Lines" is a thriller that delivers on every promise - don’t miss it.

I wrote FAULT LINES because the 1985 Mexico City earthquake never left me. I was a 28-year-old TV producer working on an NBC miniseries with Burt Lancaster when the quake hit—8.1 on the Richter scale, buildings collapsing, thousands dead. The experience shaped me in ways I didn't understand for years.
The novel grew from that memory: the chaos, the beauty, the corruption, and the way people reveal who they really are when the ground literally moves beneath them. It's a thriller, but it's also about loyalty, survival, and the fault lines that run through every choice we make under pressure.
If you read it, I'd love to hear what you think. And thank you for giving it a look.

Fault Lines review
This is a thriller that builds masterfully, culminating in the intrigue of international politics. While it is centered in Mexico City, its application extends to powerful social, political, and economic forces everywhere. A test of trust and loyalty between romantic protagonists rounds out this well-written, engaging novel by the author who has personal experience in the country and film industry about which he writes. This novel is an engaging and entertaining read: highly recommended.

Excellent book!! I couldn’t put it down! It is interesting, suspenseful and thrilling throughout its content. Typically, i don’t like or read fiction but I will reconsider my decision regarding fiction after reading this book. It is well written and I could ‘picture’ the scenes as they were revealed in the book. I look forward to additional work from Jeff Nelson and I highly recommend ‘Fault Lines’!!

Engaging from the first page, my enthusiasm for this novel was enhanced by the historic events in the background. Having been to various parts of Mexico, including Mexico City in the 1980's, and remembering the earthquake that rocked the city, I was thrilled to immerse myself in FAULT LINES. Nelson created a book that was hard to put down.

I loved the story and can certainly recommend the book to anyone who enjoys a good mystery tale (and it even has a happy ending). :)
