Pico Iyer (author fo Video Nights in Kathmandu, one of the classic travel books), wrote a book called 'Global Soul'. It was a bit long-winded, I thought, but the topic was interesting. There are more people who are really international, with ties to many countries. Iyer is of Indian descent, born in England, and raised in Santa Barbara, while attending a British public school (Eton?) and Oxford. He lives with his long-time Japanese girlfriend in Nara, Japan. It makes you think about the impact of living in many places, and raising children in multiple environments.
