Cities in Flight Retelling: Final Thoughts on Blish's Masterwork

Twenty-three posts. Four novels. A timeline that starts with Cold War paranoia in Washington and ends with the literal birth of new universes. We’re done.

I want to step back and talk about the whole thing. What worked, what didn’t, and whether you should actually read this book yourself.

The Journey

When I started this series, I said Blish was doing something bold. Now that we’ve walked through every chapter, I think bold undersells it. The man wrote a complete future history of the human race, from McCarthyism to the end of time itself.

Think about the arc we just covered.

In “They Shall Have Stars,” Senator Wagoner sits in a paranoid Washington where scientists get investigated for their college roommates. He secretly funds two projects: an antigravity engine and an immortality drug. Both succeed. He dies for it. But those two inventions send human cities flying into space for the next two thousand years.

In “A Life for the Stars,” a teenager named Chris gets press-ganged onto a flying city and has to figure out how to survive. It’s a coming-of-age story set against interstellar economics. The kid goes from scared passenger to citizen of New York City, somewhere between the stars.

In “Earthman, Come Home,” Mayor Amalfi runs New York through centuries of trouble. Rogue cops, dying economies, a Vegan orbital fort disguised as myth, and the slow collapse of the Okie way of life. He destroys the fort with a three-millimeter flick of his wrist, then takes his city out of the galaxy entirely.

And in “The Triumph of Time,” the universe is ending. Not metaphorically. The metagalactic cycle is closing. Matter and antimatter are rushing back together. And Amalfi, the old man who spent a thousand years flying cities, chooses to stand at the center of the collision and shape what comes next. His final act is to seed a new universe with the physical constants that allow life.

“Creation began.”

Two words. The last two words. And they hit like a freight train.

Why It’s Worth Reading Today

Here’s the thing about Cities in Flight. The scope is unmatched. I’ve read Asimov’s Foundation series, Herbert’s Dune, Clarke’s Odyssey books. They’re all brilliant. But Blish did something none of them quite managed: he built a future history that runs from a recognizable present all the way to cosmological collapse, and every piece connects.

The spindizzy comes from the Bridge on Jupiter. The anti-agathics come from soil samples screened in a Bronx lab. Those two inventions create the Okie cities. The Okie cities create an interstellar economy. That economy collapses. The collapse drives Amalfi out of the galaxy. And leaving the galaxy puts him in position to witness the end of everything.

Every cause has a consequence. Every book depends on what came before. That’s not just storytelling. That’s architecture.

And the ideas themselves are still interesting. Antigravity engines that can lift whole cities. Drugs that stop aging but create social problems nobody expected. An entire civilization of migrant workers in space, doing contract jobs on alien planets. The economics of interstellar labor. Blish was thinking about gig economy problems in 1955, decades before the term existed.

He was also doing worldbuilding before worldbuilding was a genre label. Spengler’s cyclical theory of civilizations isn’t just background decoration. It’s the engine that drives the plot. The Okies are the creative minority of a declining West. The Hruntan Empire is the Caesarism phase. The Web of Hercules is the next culture rising from the ashes. Blish mapped an entire philosophy of history onto a space opera, and somehow it works.

What Hasn’t Aged Well

I’m not going to pretend this book is perfect. It has problems, and they’re worth being honest about.

The prose is dense. Really dense. Blish writes in a 1950s style that assumes you’ll read every sentence twice and enjoy it. Paragraphs are packed. Technical details pile up. There are chapters where the plot stops so Blish can explain astrophysics or Spenglerian philosophy for two pages straight. If you grew up on modern sci-fi pacing, this will feel slow.

The female characters are thin. Dee Hazleton gets some good moments, especially in “The Triumph of Time” where she makes choices that matter. But for most of the series, women exist as love interests, wives, or plot devices. Anne Abbott in “They Shall Have Stars” is smarter than anyone around her, and Blish still mostly uses her as a mirror for Paige Russell’s story. This was common for the era. It’s still noticeable.

Some of the science is obviously dated. The Bridge on Jupiter, as cool as it is, doesn’t match what we know about the planet now. The anti-agathics are pure handwaving. And Blish’s cosmology in the final novel, while dramatic, doesn’t line up with modern physics. But honestly, that matters less than you’d think. The science serves the story, and the story holds up.

Who Should Read This

If you liked Asimov’s Foundation, you should read Cities in Flight. Same ambition, different flavor. Asimov gave you psychohistory and the slow rebuilding of civilization. Blish gives you flying cities and the question of what happens when a civilization has nowhere left to go.

If you like big-idea science fiction, the kind that asks questions about economics, politics, philosophy, and the nature of time, this is your book. Blish was an intellectual. He read Spengler and Toynbee and James and Comte and folded all of it into a space opera. The result is dense but rewarding.

If you’re interested in how civilizations rise, peak, and fall, this is one of the best fictional treatments of that question ever written. Blish didn’t just show you a civilization collapsing. He showed you why it collapses, and what grows from the wreckage.

And if you just want a story where a thousand-year-old mayor steers a flying New York City through interstellar space and destroys a Vegan battle fortress with a planetoid, well, that’s in here too.

My Honest Take

Cities in Flight is not an easy read. The language is old-fashioned. The pacing is uneven. Some chapters drag. The first book is the hardest to get into because Blish front-loads the politics and the science before you even know why any of it matters.

But it is a rewarding read. By the time you reach the ending, by the time Amalfi stands at the center of colliding universes and chooses to create, you feel the weight of everything that came before. Two thousand years of history. Four novels of struggle and ingenuity and loss. All building to two words.

I grew up reading science fiction in a language that wasn’t my first. Books like this one taught me that good ideas don’t need fancy words. Blish’s prose is dense, yes, but his ideas are clear. Cities fly. People live forever. Economies collapse. Civilizations fall. And sometimes, at the very end, you get to build something new.

That’s worth the effort.

The Four Novels

1. They Shall Have Stars - Cold War paranoia funds two secret projects that give humanity antigravity and immortality.
2. A Life for the Stars - A teenager gets swept into the flying city of Scranton and finds his way to New York among the stars.
3. Earthman, Come Home - Mayor Amalfi navigates New York City through centuries of interstellar politics, economic collapse, and one final battle.
4. The Triumph of Time - The universe is ending, and the last decision left is what kind of universe comes next.

Thank You

If you followed this series from the introduction to this final post, thank you. Twenty-four entries is a lot of reading, and I appreciate every one of you who stuck with it. I hope the retelling made Blish’s work more accessible, or at least convinced you to pick up the book and try it yourself.

Cities in Flight is one of those books that sits quietly on the shelf while flashier series get all the attention. But it’s a masterwork. Blish earned that SF Masterworks Volume 3 designation. And “Creation began” earned its place among the great endings in literature.

Go read it.
