Underworld by Graham Hancock

Flooded Kingdoms of the Ice Age

An investigative synthesis of underwater archaeology, geology, mythology, and remote-sensing evidence arguing that dramatic sea-level rises at the end of the last Ice Age submerged prehistoric coastal landscapes and may have erased advanced human settlements; drawing on dive reports, sonar and satellite imagery, sediment cores and flood myths, the book makes a provocative, controversial case for lost chapters of human history while engaging with mainstream scientific debate.
