Ever since her dad left them 20 years ago, it’s been just Madeline Hill and her mom on their farm in Coalfield, Tennessee. While it’s a bit lonely and a less exciting life than what she imagined for herself, it’s mostly okay. Then one day, Reuben Hill pulls up in a PT Cruiser and informs Madeline that he believes she’s his half-sister. Reuben, who was left behind by their dad 30 years ago, has hired a detective to track down their father and a string of other half-siblings. And he wants Madeline to leave her home and join him for the craziest kind of road trip imaginable to find them all. As Madeline and Reuben --- and eventually the others --- share stories of their father, who behaved so differently in each life he created, they begin to question what he was looking for with every new incarnation.
