Navy SEAL widow Taya Kyle calls her new book a "love letter to the country."
Kyle told Robin Roberts on "Good Morning America" that the book, "American Spirit," is filled with stories and profiles of everyday heroes.
"It's like, you have a friend -- you watch struggle and you say, 'I know you're angry. You're hurting. I see your soul. Your soul is good,'" she said. "That's how I look at this country. It's my love letter to the country. I see that we're angry and hurting. I see we're so much more than politics, so much more than these issues. We're good, we have soul, we have character. There are so many people doing good things and I want people to see that."
Kyle said she included stories from all Americans with a "pioneering spirit" -- young, old and from different backgrounds.
"I want people to know it's happening all around you. Open your eyes, consider getting involved," she explained.
Kyle said one Air Force veteran, whose story is in the book, has helped create a community for other veterans.
"Donny Davis is a great guy. He had PTSD and he became a pastor to help other people. He ended up with a property he bought and he puts tiny houses on it -- for veterans," she said. "He's just getting started. It's awesome to see the corporations backing it," she added about Operation Safe Haven. "People get it, they care."

"Everyone says the next [generation] is going to ruin the country. And we rally. I'm looking at these kids going, there are so many good kids out there doing awesome things," she said. "We need the remember that."
The mother of two, whose husband Chris Kyle died in 2013 after his service as a Navy SEAL sniper in four tours during the Iraq war, said her family is "fantastic."
"They're funny, they're growing up. They're just a blast to hang out with," she gushed. "I'm doing well too, which is a nice thing to be able to say after all this time."
She credited the stories in the book as "one of the reasons" that has helped her to stay positive.
"The world is full of good. It's not all rough and hard. And when it's rough and hard, there's good [that comes] from it," she explained.
She also credited her own faith for the good in her life.
"It's my faith 100 percent. I know it's God. I have seen him so much in my depths," she said. "The hard things in life have brought you more joy when you get through it."
