The HAB Theory is a 1976 science fiction novel by American author Allan W. Eckert. The novel is from the apocalyptic fiction subgenre. Eckert believed that the real-world facts and conclusions he quoted in the novel, were worthy of further exploration... The book explores a version of pole shift hypothesis postulated by Professor Charles Hapgood in two volumes, plus the 1967 book Cataclysms of the Earth by Hugh Auchincloss Brown.
