*The Earthquake Child* is the story of an adoption, told through the voices of an adoptee, his desperate young birth mother, and his loving but grieving adoptive mother. How can Joshua’s behavior be explained? This question is all-consuming for his adoptive family. Joshua was relinquished at birth, then adopted only days later. Is it his genetic inheritance of substance abuse and generational poverty that causes him to act out, run away and eventually become involved with drugs? Is it the losses he’s experienced in his adoptive family? Or is it the very fact of adoption itself—the trauma of being amputated from his gestational mother to be raised by a family unrelated to him by blood, culture, or biology? What makes our children who they are? These voices and questions will resonate with all parents, but particularly with those who are or have been part of the adoption triangle: adoptees, mothers who have relinquished a child, and parents who’ve added a child to their family through adoption.
