It’s big. It’s messy. It’s 600-plus pages of psychological debris. Honestly, if you pick up the Tree of Smoke book expecting a standard "boots on the ground" war story, you’re going to be very confused. Denis Johnson didn't write a history book. He wrote a ghost story where the ghosts are still alive, wandering through the jungles of Southeast Asia and the hallways of the CIA.
War is loud, but this book is mostly about the whispers.
National Book Award winner for 2007. Finalist for the Pulitzer. You’ve probably seen those stickers on the cover. But what do they actually mean for you as a reader? It means Johnson captured something that most war novelists miss: the sheer, hallucinatory paranoia of the mid-century American intelligence machine. This isn't just about bullets; it's about the lies we tell ourselves to justify the chaos.
The Chaos of Skip Sands and the Myth of Information
At the center of this sprawling web is William "Skip" Sands. He’s a CIA recruit, but not the James Bond kind. He’s more of a filing clerk with a soul-crushing weight of expectation on his shoulders. He works for his uncle, the Colonel—a man who is basically the personification of American hubris in the 1960s.
The Colonel is obsessed with "Tree of Smoke." That's the code name for a massive psychological warfare operation. The goal? To create a false narrative so dense and believable that the enemy (and maybe even the Americans) can’t tell what’s real anymore.
It's a dizzying concept.
Think about it. In the Tree of Smoke book, information isn't power. It’s a burden. Skip spends his time cataloging people, building files, and trying to find a signal in the noise. But the noise is all there is. Johnson writes with this jagged, poetic rhythm that makes you feel the humidity of the jungle and the stale air of a windowless office. You’re trapped with Skip as he realizes that the "intel" he’s gathering is basically a collective hallucination.

Why Denis Johnson's Style Feels Different
Most writers try to be invisible. Johnson doesn't. He’s right there with you, shaking the camera.
His sentences don’t follow the rules. Sometimes they’re short. Brutal. Like a punch. Other times, he goes on these long, lyrical runs that feel like a fever dream. It mimics the experience of being in a conflict that has no clear front line. You’re in Vietnam, then you’re in the Philippines, then you’re back in a flashback, and suddenly you’re looking through the eyes of two brothers from Arizona, Bill and James Houston, who represent the raw, bleeding edge of the infantry experience.
The Houstons are the counterbalance to the high-level spy games. They aren't worried about "Tree of Smoke" as a concept; they’re worried about mud, rot, and the fact that they’re losing their minds. By weaving these low-level grunts together with the high-level spooks, Johnson creates a 3D view of the war.
It's exhausting. It’s meant to be.
If you read this book and feel a bit lost, you’re doing it right. Johnson is showing you that the people running the war were just as lost as the kids carrying the rifles. There’s a specific scene where characters are discussing the nature of the soul and the "intelligence" of the universe while people are dying just a few miles away. That’s the core of the Tree of Smoke book—the gap between our lofty ideas and the ugly reality of dirt and blood.
The Religious Undercurrent You Can’t Ignore
There’s a lot of talk about God in this book. Usually, war books focus on the absence of God, but Johnson—who often explored themes of grace and redemption in his other work, like Jesus' Son—does something different here. He shows people trying to find a spiritual justification for the unjustifiable.

Skip Sands wants to believe in a higher purpose. The Colonel thinks he is the higher purpose.
And then there’s Kathy Grissom. She’s a Canadian nurse, a widow, and she’s the moral compass of the story, even if that compass is spinning wildly. Her relationship with Skip is one of the few things in the book that feels "human" in a traditional sense, but even that is tainted by the environment. Everything in this world is smoke. You try to grab it, and your hand just passes right through.
What Most People Get Wrong About the Ending
People complain about the ending of the Tree of Smoke book. They say it’s too long or that it drifts off into a weird post-war epilogue.
They’re missing the point.
The war didn't just "end" in 1975. For the people involved, it trailed off into decades of trauma, conspiracy theories, and hollowed-out lives. The final sections of the book, which follow the characters into the 1980s, are essential. They show the "smoke" finally clearing, only to reveal that there’s nothing underneath.
The operation failed. The people broke. The world moved on, but they couldn’t.

If Johnson had ended with a big cinematic battle, it would have been a lie. Instead, he ends with the quiet, lingering sadness of people who realized they were part of a myth. It’s one of the most haunting conclusions in modern literature because it refuses to give the reader the "closure" we crave.
How to Actually Read This Book (Without Giving Up)
Let's be real: this is a dense read. If you try to track every single minor character and every acronym, your brain will melt. Here is how to actually enjoy it:
- Accept the fog. Don't stress if you don't understand the specifics of every intelligence plot. Neither does Skip.
- Focus on the Houstons. When the spy stuff gets too heady, look to the Houston brothers. They are the emotional anchor.
- Read for the prose. Johnson is a poet first. Some of the descriptions of the light hitting the trees or the sound of a helicopter are worth the price of admission alone.
- Look for the "Chimera." The book talks a lot about things that aren't there. Keep an eye on how often characters react to things that turn out to be illusions.
The Tree of Smoke book remains a massive achievement because it doesn't try to explain Vietnam. It tries to be Vietnam. It’s a sensory experience that forces you to confront the idea that maybe nobody really knows what they’re doing, especially the people in charge.
Practical Steps for the Serious Reader
If you’re ready to tackle this beast, don't just dive in blindly.
First, get a physical copy. You’ll want to flip back and forth to remember who certain characters are, and that’s a pain on an e-reader.
Second, read about the real-life "Phoenix Program." While Johnson’s "Tree of Smoke" is a fictionalized operation, it is heavily inspired by the very real, very controversial CIA programs used for "neutralization through assassination" and psychological operations during the war. Understanding that this isn't pure fantasy makes the book significantly more terrifying.
Lastly, pair this with Michael Herr’s Dispatches. Herr was a journalist who captured the "vibe" of the war in non-fiction, and you can see his influence all over Johnson’s writing.
This isn't a book you finish and forget. It’s a book that sits on your shelf and stares at you, reminding you that the world is a lot more complicated—and a lot more fragile—than we like to admit. Go find a copy, clear your weekend, and get ready to get lost in the smoke. There is no better way to understand the American psyche of the 20th century.
