This title includes a brilliant mix of vivid reportage, history and science. Historical diving bells, Greek sponge divers, world war two frogmen and record-setting breath hold divers compete for space with misunderstood sharks, weeping turtles, smiling dolphins and erotically shaped sea slugs. From Ireland to Florida, Papua New Guinea to Vienna and the Bahamas to Seychelles, ''Neutral Buoyancy'' is travel writing of the most fascinating, readable kind; providing a window - or a view from a glass bottomed boat - on a rich, unfamiliar and unique destination. Travel writing of this quality makes ''Neutral Buoyancy'' a must for all armchair travellers, not just divers.
