In Who's My Daddy? Gina Cameron tackles the questions Why did my mother lie about my paternity? and Why did so many other mothers hide the truth from their children? After discovering, in her mid-sixties, that her father was not her biological father, Cameron embarked on a search for her paternal roots. Her quest for answers led to her mother's tumultuous history as a refugee from Latvia in WWII and ultimately to an exploration of human evolution, tracing the arch of history from matriarchy to patriarchy. Along the way, she navigates the twists and turns of finding her paternal family and, by mining memories from her past, exposes the damaging consequences secrets and lies have on family relationships. The memoir is both an intimate portrayal of the author's own life and a look at the larger forces at play in all of our histories.
