The Birth of a Grandfather

From the publisher:

This is the story of the Wyeth family, set in Cambridge, Massachusetts (and in the summer, Maine): the very old, who are looking back; Sprig and his wife Frances, who are finding their way in the midst of youthful hopes that refuse to fade away; and the young, embarking on adulthood, sometimes with anger. As Sprig struggles to reach past his reserve so that he can be there for his wife and children, and for a friend who needs him, the other characters likewise find their way to what self-fulfillment means.
