Ball writes of water's origins, history, and unique physical character, and his exploration of water on other planets highlights the possibilities of life beyond Earth. H2O also examines the grim realities of depletion of natural resources and its effects on the availability of water in the twenty-first century.
Philip Ball is Associate Editor for the Physical Sciences with Nature. His first book was described by the TLS as 'a tour de force of popular science writing'. His second was described by the New Scientist as 'outstanding...beautifully written. If you buy no other science book this year, I suggest you buy this one.'
