This is a recently published book about the death of 19 year old Michael Rockefeller in 1961. He was Nelson's son and in New Guinea to look for so-called primitive art. He was never found, but you know in the first few pages that he was killed and eaten by the locals. So the book is about the author's quest to solve the mystery of what happened to him. A subtext is the whole Rockefeller family interest in art -- I didn't know Nelson funded the first primitive art museum in NYC. This book has been well-reviewed and I am really enjoying it.
