The Drowned World (Broché)

Fluctuations in solar radiation have caused the icecaps to melt and the seas to rise. Nature is on the rampage. London has been transformed into a primeval swamp, and within its submerged landscape giant lizards, dragonflies and insects compete for dominance. Human fertility is in decline and buildings sink beneath waters infested with decaying matter. Into this wasteland a group of intrepid scientists venture to record the flora and fauna of this new Triassic Age.
Soon ghostly voices haunt their waking and nightmares permeate their sleep ... First published in 1962, Ballard's mesmerising and ferociously imaginative novel gained him widespread critical acclaim and established his reputation as one of Britain's finest writers of science fiction.
