The book that influenced writers from Carl Sagan to Stephen Hawking, Flatland is set in a two-dimensional world where life exists only in lines and shapes - until one of its inhabitants, ''A. Square'', has his perspective transformed forever. This brilliantly eccentric classic is an invitation to see beyond our own reality.''At once a playful brainteaser about geometry, a pointed satire of Victorian manners - and a strangely compelling argument about the greatest mysteries of the Universe'' Wall Street Journal''Flatland could lead to very profound thought about our Universe and ourselves'' Isaac Asimov
