Though Iris Stern considers herself a modern woman, with a successful academic career and a happy marriage, she still holds steadfast to her old-fashioned sensibilities. But as the mother of three adult children, each with their own lives and burdens to bear, she often finds those sensibilities called into question when confronted with the choices her children have made. Through separations and reunions, the changes we cannot avoid and the love that sustains, Iris will weather whatever lies ahead with a faith that cannot be shaken. Like the inmost rings of a tree that abide through the generations, she will be as strong as heartwood.
