Abby sits with her birth and adoptive families. She has a genetic disease, MMA, and is waiting for a liver transplant. She was born in America while her Chinese birth parents were obtaining their doctorates in chemistry. They didn’t have the medical capability to care for Abby at their home in Beijing. Abby's only chance at life was adoption. Catherine and Dave adopted Abby, knowing she had complex medical needs. She is their daughter. Abby is loved deeply and selflessly by everyone here.
