“I wrote this book because I wanted everyone to know what a remarkable man my son Beau was, and what a powerful relationship he had with his family,” Biden told PEOPLE. “Honor, duty, responsibility: the values that Beau held dear are the things that continue to inspire us as a family every day. I wanted to share that. And in sharing it, I hope I can help others who have endured what we’ve endured to find hope, solace and purpose.”

Beau Biden was lawyer who served as the former attorney general of Delaware from January 2007 to January 2015. He was diagnosed with brain cancer nearly two years before his death in May 2015. He died at the age of 46.

The title of the book was inspired by a conversation Biden had with son during their last Thanksgiving together in 2014.
