“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 magazine in an interview published Thursday.

“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, 46, died in May 2015 from a rare form of brain cancer. The Bronze Star winner was a former Delaware attorney general.

The New York Times reported last month that Beau Biden told his father on their last Thanksgiving holiday together, “Promise me, Dad. Give me your word that no matter what happens, you’re going to be all right.”

Joe Biden’s wife, Dr. Jill Biden, is also reportedly writing a book for the same publisher.

The 74-year-old former vice president has been floated as a possible 2020 White House contender. He has been vocally critical of the Trump administration, most recently taking issue with the president's claim that "both sides" shared blame for the violence at a white supremacist rally in Charlottesville, Va.
