At the age of 54, author Dani Shapiro took a DNA test and received the shocking news that her father was not her biological father. That discovery led her on a quest to track down her biological father (and half-sister) and unlock the secrets of her own identity, all of which is suspensefully chronicled in her book Inheritance: A Memoir of Genealogy, Paternity, and Love. Dani is also the host of the popular podcast "Family Secrets" and author of four other memoirs and five novels.
