A Change in Altitude by Anita Shreve
Margaret and Patrick have been married just a few months when they set off on what they hope will be a great adventure-a year living in Kenya. Margaret quickly realizes there is a great deal she doesn’t know about the complex mores of her new home, and about her own husband.
A British couple invites the newlyweds to join on a climbing expedition to Mount Kenya, and they eagerly agree. But during their harrowing ascent, a horrific accident occurs. In the aftermath of the tragedy, Margaret struggles to understand what happened on the mountain and how these events have transformed her and her marriage, perhaps forever.
