Bluebell Windows (Rising Family #3)
Susan Sallis

March, the eldest, the most difficult, loves but cannot trust her clever, manipulating husband.He deserted her once and she has never quite forgiven him.
May has her own worries - a son who seems more than usually promiscuous, and a husband who grows more attractive and handsome even as she approaches her fortieth birthday.
April has a husband she loves, and two small, gentle daughters. But she is the only one who knows that Davina is not her husband's child.
