In the 21st century, fluctuations in solar radiation have caused the ide-caps to melt and the seas to rise. Global temperatures have climbed, and civilization has retreated to the Arctic and Antarctic circles. London is a city now inundated by a primeval swamp, to which an expedition travels to record the flora and fauna of this new Triassic Age. This early novel by the author of CRASH and EMPIRE OF THE SUN is at once a fast paced narrative, a stunning evocation of a flooded, tropical London of the near future and a speculative foray into the workings of the unconscious mind.
