What to read after Davy?

Davy is set in the far future of our world, in the fourth century after the collapse of what we describe as the twentieth-century civilisation. In a land turned upside-down and backwards by the results of scientific unwisdom, Davy and his fellow Ramblers are carefree outcasts, whose bawdy, joyous adventures among the dead ashes of Old-Time culture make a novel which has been hailed as "a frightening, ribald, poignant look at the imaginary future," as "this chilling and fascinating book," as "superb entertainment - unique," as "so unusual as the make it both refreshing and thought provoking."
