The Forgotten Affairs of Youth by Alexander McCall Smith

The Forgotten Affairs of Youth is the next chapter in the life of Isabelle Dalhousie, editor, philosopher, denizen of Edinburgh. We learn more about Isabelle's relationship with her fiance, Jamie, and her prickly relationship with her niece, Cat. Isabelle also gets involved in helping an Australian philosopher named Jane track down her long-lost family in Scotland. Nothing earth-shaking happens in these books but they're a pleasant way to pass the weekend.
