Paige Meyer thinks there must be a mistake when she gets an email from FamilyTree.com announcing a new parent-child match. Then she realizes the man she grew up calling “Dad” is not her biological father. Back in 1975, Betsy Kaplan is a sophomore at the University of Kansas. She’s in a serious relationship with a man who is decent, kind and just a little boring. When a well-intended gift goes wrong, Betsy takes it as a sign that she should end their relationship. The same night Betsy broke up with her boyfriend, Andy Abrams ended his own relationship. Upset and terrified that a secret he’d kept his whole life might be revealed, he tries to drown his sorrows in whiskey and a pretty girl. Paige attempts to come to terms with this new information, and how it impacts everything she thought she knew about herself. When she can’t get answers from her mother, she goes looking for the truth from the only other person who was there that night.
