“Book Descriptions: "Dear Sam," the first letter began, "As your only living grandfather, I wanted to welcome you into this world. Always remember that...life is a gift and a blessing."

But only 14 months after his first note, grandfather Dan received terrible news: Little Sam had been diagnosed with pervasive developmental disability, a form of autism. At that moment, the letters took on a new meaning and urgency.” DRIVE
