Hoffman of "The Lunatic Express" goes off in search of the real story behind the mysterious disappearance of Michael Rockefeller (son of Nelson) in the 1960s. The young Harvard grad was last seen attempting to swim to shore off the coast of New Guinea and stories began circulating that he'd been killed by a cannibal tribe. This version of events was denied by his family and the Dutch government and it was concluded that Rockefeller had drowned. Nelson calls the book "fascinating." "He was just this guy who went off in search of adventures," she says of Rockefeller.
