In today’s episode, guest Dani Shapiro talks about her recent New York Times best-selling memoir, Inheritance, and how she’s been circling around family secrets for her entire life. She reveals how the secret she never knew, until recently—that the father who raised her was not her biological father—is likely the thing that made her a writer. In this deep conversation with co-hosts Brooke and Grant, Dani delves into the “unthought known,” the impact of those things we withhold, and how the particular family secret of parents not revealing a child’s identity to them is nearly an obsolete idea due to genetic testing sites like 23andMe.
