The Nelsons really are impressive for forgiving the driver responsible for the death of their son in a car accident in the fall, and I'm not the only one who's noticed.
They're featured in the new book Why Forgive? By Johann Christoph Arnold, who met Trish at a school assembly where she was speaking about Zack. The section is brief, but it deals with their ability to move on and their struggle with it.
There's a free ebook online here, plus paperback copies on Amazon.
