Rumaan Alam’s novel, Leave the World Behind, is essentially a masterclass in making you feel like something is crawling under your skin. It’s a book about a vacation. Well, it starts that way. It’s also about the end of the world, maybe? Honestly, the ambiguity is exactly why people are still arguing about it years after its 2020 release and the subsequent Netflix adaptation.
The plot is deceptively simple. A middle-class white family—Amanda, Clay, and their two teenagers—rent a luxury Airbnb in a remote corner of Long Island. They want to escape the city. They want to buy expensive groceries and pretend they are the kind of people who truly belong in a house with a pool. Then, a knock comes at the door in the middle of the night. It’s an older Black couple, G.H. and Ruth, who claim to be the homeowners. They say there’s been a massive blackout in New York City. They’re scared.

What follows isn’t a typical horror story. There are no zombies. No aliens land on the front lawn. Instead, Alam leans into the social friction and the terrifying realization that in a crisis, your money, your race, and your Google Maps app won't save you.
The Anxiety of Leave the World Behind
Why does this book work? Because it preys on very specific, very modern fears. We rely on our phones for everything. When the internet goes down in the book, the characters don't just lose TikTok; they lose their tether to reality. Without a news feed, how do you know if the world is actually ending or if it's just a local power outage?
Alam’s writing style is aggressive. He uses an omniscient narrator who knows things the characters don't. While Amanda is worrying about whether the milk is going bad, the narrator casually mentions that thousands of people are dying elsewhere. It creates this brutal contrast between the mundane and the catastrophic.
The racial dynamics are the real engine of the first half. Amanda’s immediate suspicion of G.H. and Ruth isn't overt "bad guy" racism; it's that subtle, ingrained bias where she can't believe a Black couple could own a house this nice. It’s awkward. It’s painful to read. It's supposed to be.
What Actually Happens to the Animals?
One of the most frequent questions readers have involves the deer. Thousands of them suddenly appear, staring at the house. Then there are the flamingos in the pool.

In a traditional thriller, these would be omens. In Leave the World Behind, they are symbols of nature being completely "shook" by whatever man-made disaster is happening in the background. Many ecological experts note that animals often sense seismic or electromagnetic shifts long before humans do. By the time the characters notice the deer, the "old world" is already gone.
Comparing the Book to the Movie
If you’ve only seen the Julia Roberts movie, you’re missing the internal rot that makes the book so heavy. Director Sam Esmail made the film more of a spectacle. He added the "noise"—that ear-splitting sonic boom that cracks glass. In the book, the noise is there, but the psychological erosion is much slower.
The ending is where most people lose their minds. The movie gives us a bit more "closure" with Rose finding the bunker and starting Friends. The book? The book is much bleaker. It suggests that even if you find a bunker, what are you actually saving? A life of eating canned peaches while the rest of humanity vanishes?
The Realism of the Collapse
Is the scenario in Leave the World Behind scientifically possible? Sort of. A massive cyberattack on the power grid is a top-tier concern for national security experts. If the GPS satellites went down—as suggested in the story—transportation and logistics would freeze instantly.
We saw a micro-version of this during the early days of the COVID-19 pandemic. Remember the run on toilet paper? Now imagine that, but the lights are out and your car won't start.
Why the Ambiguity Matters
People hate not knowing. We want to know if it was a cyberattack, a nuclear strike, or a revolution. Alam refuses to say. This choice is brilliant because it puts the reader in the exact same position as the characters. You are trapped in that house with them, guessing.
The book argues that information is a luxury. In a true collapse, you wouldn't get a tidy explanation from a news anchor. You would just be in the dark.
Actionable Takeaways for Readers and Fans
If the themes of this book hit a little too close to home, or if you're looking to dive deeper into this specific brand of "literary apocalypse," here is how to process it.
- Read the Source Material: If you’ve only watched the film, buy the book. The prose is jagged and uncomfortable in a way a screen can’t replicate.
- Explore the Genre: If you liked the "closed-door" tension, check out The Mist by Stephen King or Severance by Ling Ma. They deal with the same "what do we do now?" energy.
- Audit Your Own Reliance: Look at how the characters react to the loss of technology. It’s a great (if slightly terrifying) prompt to think about basic analog skills—maps, first aid, knowing your neighbors.
- Discuss the "The Noise": Many readers interpret the physical symptoms the characters feel—the teeth falling out, the headaches—as radiation sickness or a directed energy weapon (like Havana Syndrome). It’s worth researching the real-world effects of long-range acoustic devices (LRADs) to see how close the fiction is to reality.
- Support Local Libraries: If you're looking for Alam's other work, like That Kind of Mother, your local library is the best place to find his earlier explorations of race and class without the end-of-the-world stakes.
The ending of the story isn't a cliffhanger. It's a period. The world they knew is over. The challenge for the reader is to decide if the characters are worth rooting for once all their toys are taken away.

The reality of the situation is that we are all much closer to Amanda and Clay than we’d like to admit. We assume the system works because it has always worked. Leave the World Behind is the reminder that the system is actually quite fragile. It’s a haunting, unpleasant, and necessary read that doesn't offer any easy answers. It just leaves you sitting in the dark, wondering what that noise outside was.
