Ishamael - daniel quinn. A cautionary tale describing how human evolution is now dominated by a group of humans called the 'takers'', who will end up destroying the world. The author, through the story of a captive ape called Ishmael, guides out understanding to what he believes is a better way - or at least a social evolutionary seperate branch - the 'leavers' who were the nomadic peoples oppressed since Cain (agrarian culture) destroyed his brother (the nomads) Abel. All good stuff with a good message - makes you think, but not too hard as its written in simple American esoteric-speak.
