Austin Eggleston, 15, was in the hospital and running out of time.
"We had some deep, dark conversations," said his mother, Mary Anglin. "At the age of 15 you understand what's going on."
Born with a literal broken heart that required five surgeries and four pacemakers to keep ticking, Austin was in dire need of a transplant, waiting four months for a miracle at Lurie Children's Hospital of Chicago. Then his pediatric cardiologist walked in.
Dr. Philip Thrush told Austin, a "Star Wars" fan, that when the news was good, he would deliver it in costume, as Chewbacca. When it finally happened, Austin had one incredible reaction.
