In the novel Earthman, Come Home, the third book in the Cities in Flight series, shorter works are joined into a story about the Mayor of New York as the city travels between the stars looking for work. The book, is not a good novel, but it is a great anthology. The attempts to smooth over the changes between the four parts do not work to join them together into a larger story. The stories remain stories with a common theme, but there is nothing wrong with that. It is well worth reading and one novella, Sargasso of Lost Cities, is one of Blish’s best.
