Jack loves and misses his bus-driving grandfather. When Grandpa Nod got sick, Jack's mother said eight-year-old Jack was too young to visit his grandfather in hospital. When Grandpa Nod died, Jack's mother said Jack was too young to go to the funeral. One day after school, Jack gets on the wrong bus. To his surprise he discovers Grandpa Nod is in the driver's seat of the empty bus. Grandpa Nod takes him to all the places Jack was too young to go-the hospital, the funeral home and the cemetery. By the end of the ride, Jack has had the chance to tell his grandfather how much he misses him. And with his birthday coming soon, Jack receives a very special gift-Grandpa Nod's bus schedules. So even if he does get on the wrong bus, Jack will always be able to find his way home.
