Glenn was in Shreveport, Louisiana on Friday, at Barnes & Noble where hundreds showed up for a book signing for his new book, The Immortal Nicholas .
"I met some of the best people I've met. I mean, just really dirt strong people," Glenn said on radio Monday. "Every single person I met in line was just amazing."
He went on to describe one young woman in particular, who "just lit up the room." When she handed Glenn her copy of the book, Jennifer asked if he could sign it to her step-father, explaining it was really important. Glenn obliged --- then, she reached into her pocket and handed Glenn a letter.
In the letter, which Glenn read on the drive home, she described how much she wanted to get her step-father something special, "because he's my hero."
She wrote:
"I never knew a dad that wanted to be a good man until my stepdad came into my life. It takes a special kind of person to choose to love kids that aren't yours. He did one better --- He chose to make us his --- He chose Danielle and I every chance he got. He's that kind of dad."
Jennifer went on to write how her step-father had recently lost his job, and how reading The Immortal Nicholas gave her new perspective on what matters most in life.
"The first two chapters made me question what really was important," she wrote. "I want to make sure that my dad doesn't forget what's important and why we love him. I want to make sure he knows that we'll pick him every chance we get as well. Not because of what he offers us with his job or his wallet, but because he gave us his heart when our biological dad couldn't or wouldn't.
Glenn shared the entire letter on radio.
"I love this letter," Glenn said. "This gives me hope."
Jennifer wasn't the only person who gave Glenn a letter that day. Below is Glenn received from a young fan named Rhodes, who showed up to the book signing with his parents.
