The Mistress's Daughter by A. M. Homes
This acclaimed writer was given up for adoption before she was born. Her biological mother was a twenty-two-year-old single woman who was having an affair with a much older married man with a family of his own. This is the ruthlessly honest account of what happened when, thirty years later, her birth parents came looking for her. Homes relates how they initially made contact and what happened afterwards, and digs through the family history of both sets of her parents in a twenty-first-century electronic search for self. Daring, heartbreaking, and startlingly funny, Homes's memoir is a brave and profoundly moving consideration of identity and family.
