Mutant Message Down Under - Marlo Morgan.

This one should be required reading. The author says that this is a true story. An American woman is abducted by an aboriginal tribe and goes on a "walkabout" with them across Austrilla. She learns much about herself and they give her a message to give to the rest of the world, as they have decided collectively that they no longer have a place on this planet that will soon die if we don't start to take care of it. Many spiritual truths are presented in creative and interesting ways and demonstrate how they can be integrated into actual life experiences. Very Inspirational.
