Cities in Flight

James Blish's epic four-novel omnibus spanning from Cold War politics to the literal end of the universe, following flying cities through thousands of years of future history.

Cities in Flight collects four novels written between 1950 and 1962 into one massive future history. The setup is simple but wild: humanity discovers antigravity engines (spindizzies) that can lift entire cities off Earth, plus drugs that stop aging. Put those together and you get whole cities full of immortal people flying through space looking for work. They’re called Okies, named after the Dust Bowl migrant workers.

The first novel, They Shall Have Stars, is set in a near-future Cold War world where two secret projects - a drug research lab in New York and a massive engineering project on Jupiter - lead to the discoveries that change everything. A Life for the Stars follows a teenager press-ganged aboard a flying city, learning how this strange new civilization works. Earthman, Come Home is the big one, following Mayor Amalfi as he runs New York City through centuries of interstellar travel, dealing with corrupt authorities, dying civilizations, and economic collapse. The Triumph of Time brings it all to an end - literally, as the universe itself faces destruction and the characters must decide how to face the end of everything.

Blish built the whole thing on Oswald Spengler’s philosophy about how civilizations rise and fall in predictable patterns. It gives the series an intellectual weight that most space opera doesn’t have. The writing is dense 1950s sci-fi prose, but the ideas are enormous. If you like Asimov’s Foundation or big-picture science fiction that spans millennia, this is essential reading.

Cities in Flight Retelling: Earthman Come Home Part 1 - New York in Space

We are now in the third novel of Cities in Flight, and this is the big one. “Earthman, Come Home” is the longest book in the collection, and it shifts focus to the character who matters most in this universe: Mayor John Amalfi of New York City. Not New York on Earth. New York flying through space, powered by spindizzy engines, looking for work among the stars.

Cities in Flight Retelling: Earthman Come Home Part 6 - The March on Earth

In Part 5, we saw the jungle of Okie cities gathering near a red dwarf star, desperate for work. An Acolyte entrepreneur showed up offering terrible wages, things got violent, and Lieutenant Lerner’s cops accidentally blew up a bystander city. Amalfi watched it all and decided it was time to visit Buda-Pesht, the King’s city, in person. He brought Hazleton and Dee along. And now things get political.

Cities in Flight Retelling: Earthman Come Home Part 7 - The Battle of Hern VI

Amalfi is turning a dead rock into a weapon. Hern VI is a planetoid, small and ugly, and his people are bolting spindizzy engines all over it. The work is brutal. Every driver has to be placed at exact compass points, locked to the center of gravity, balanced against every other machine. And there still aren’t enough to make the thing fully steerable. When this rock finally flies, it will be clumsy and wild. But it will fly.
