Pulitzer Prize-winning author David Finkel is well-known for his embedded reporting and immersive journalism. In his latest book “An American Dreamer,” he observes two decent and damaged men navigating the deep political divides in today’s America. The novelistic nonfiction book chronicles the lives of ordinary Americans who search for common ground in a country that is becoming increasingly fractured. Finkel talks about what he learned writing the book, about the two men whose lives he chronicles, and whether we are all living through a defining moment in history.
