Where Or When by Anita Shreve
When Charles Callahan chances on a newspaper photograph of Sian Richards, a woman he loved when they were both only thirteen, he is hardly in a position to do anything about it. He has been faithfully married for years and his Rhode Island real estate business has been hit hard by the recession. He is scrambling to stave off bankruptcy and save his house. But Charles cannot resist the hand of fate. He writes to Sian, now a poet living with a family of her own on a farm in upstate New York.
Three decades after they last saw each other, the two lovers meet. Powerfully drawn together once again, Charles and Sian are forced to come to terms with the nature of erotic love and betrayal, moral quandaries in an age of shifting values, and the elusive nature of time. Struggling to reclaim what once they lost, they set in motion a passionate and tumultuous series of events that moves to a shocking conclusion.
