Thirty-eight years later, a second message is received and Sarah, now 87, may hold the key to deciphering this one, too... if she lives long enough. A wealthy industrialist offers to pay for Sarah to have a rollback—a hugely expensive experimental rejuvenation procedure.

    Named after the migrant workers of America's Dust Bowl, these novels convey Blish's "history of the future," a brilliant and bleak look at a world where cities roam the Galaxy looking for work and a sustainable way of life.In the first novel, They Shall Have Stars, man has thoroughly explored the Solar System, yet the dream of going even further seems to have died in all but one man. His battle to realize his dream results in two momentous discoveries anti-gravity and the secret of immortality. In A Life for the Stars, it is centuries later and anti-gravity generations have enabled whole cities to lift off the surface of the earth to become galactic wanderers. In Earthman, Come Home, the nomadic cities revert to barbarism and marauding rogue cities begin to pose a threat to all civilized worlds. In the final novel, The Triumph of Time, history repeats itself as the cities once again journey back in to space making a terrifying discovery which could destroy the entire Universe. A serious and haunting vision of our world and its limits, Cities in Flight marks the return to print of one of science fiction's most inimitable writers.A Selection of the Science Fiction Book Club
