Flood is a 2008 work of hard science fiction by English author Stephen Baxter. It describes a near future world where deep submarine seismic activity leads to seabed fragmentation, and the opening of deep subterranean reservoirs of water. Human civilisation is almost destroyed by the rising inundation, which covers Mount Everest in 2052. Baxter issued a sequel to this work, entitled Ark, in 2009. Flood was nominated for the British Science Fiction Award in 2008.
