The vow
Luke is not yet twelve when his doctor father dies of a heart attack, leaving him an orphan. Small for his age and something of a loner. Luke goes to live with his Uncle Henry and Aunt Helen in Collingwood on Georgian Bay, where Uncle Henry has a saw mill on the edge of town. The aunt and uncle have no children of their own and there are difficult days for both the boy and the adults as they try to get used to each other.
