For centuries, humans have compared the purity of water with the purity of diamonds. The highest quality diamonds are known as 'diamonds of the first water'. But can you drink a diamond? Ice caps are melting. Seas are rising, coastlines disappearing. The global water wars are coming. By 2030, says the UN, the globe will be in water crisis. In a world full of riches, the scarcest, the most valuable, is water. One woman has put it all together: Nix Meyer is an uplifting example of how one person can inspire the world to environmental wisdom. She can't move mountains, but she'll move an iceberg--across the Pacific Ocean. She brings water to those who need it--and to those who don't. What really motivates us to do what we do? Only our dreams know our deepest desires and fears. Meet Miles Dormer, the young Kiwi who dreams the dreams of the dreamer. Can he discover who values diamonds over water, before the world dies of thirst?
