The Water Knife

...or it will: the Water Wars. When California, Nevada, New Mexico and Arizona start fighting over where their water comes from - and the refugees start moving. I've been to Phoenix, and marvelled at how a place like that flourishes in the absence of water. Las Vegas too: they have no right to be there, brash and big and water-hungry, with their golf courses and watered gardens.

This is a brutal, stark book. It pulls no punches, and throws a lot in your face - but it's very good. I don't give it five stars because it's just a bit TOO bleak.
