Cities in Flight, Vol. 1

"Spanning the far-distant future and the infinite reaches of space, Cities in Flight brings together the famed "Okie" novels - named after the migrant workers of America's Dust Bowl - of science fiction master James Blish. Featuring flying cities roaming the galaxy looking for work and a sustainable way of life, the four volumes in Cities in Flight take us from the death of our universe to the birth of the next.". "Blish's classic is built on two crucial discoveries: antigravity devices - "spindizzies" - which allow whole cities to be lifted from Earth to become giant spaceships, and longevity drugs, which enable the cities' inhabitants to live for thousands of years."--BOOK JACKET.
