Simple. FUN. with layers to the book - everytime you read it, it has a different level to it, yet the book never sacrifices its spirit of simplicity and joy. irreverent at times, it makes you think, see things for yourself, not your basic 'ready-made-nirvana-just-read-it' kind of book. no pretensions either.
Wise but not stuffy.
AND its a good read to boot! Picked it up because of the title [after all anyone who could create a species as contrary as the humans HAD to have a sense of HUMOR!;-)] and its been a favorite since - in both good times and sad.
HAVE FUN ALL
