* A compelling and brilliant novel about the fragility of a new marriage, from one of the greatest chroniclers of the mysteries of the heart

Newlyweds Margaret and Patrick set off on a great adventure -- a year living in Kenya in a dizzying and sometimes dangerous city. Shuttling between expat suburbs and squalid shantytowns, Margaret realizes there is a great deal she doesn't know about the complex culture of her new home, and about her husband. The newlyweds eagerly take part in a climbing expedition to the summit of Mount Kenya. But during their arduous ascent a horrific accident occurs. In its aftermath, Margaret struggles to understand what happened on the mountain and how it has transformed her and her marriage, perhaps for ever. When small actions have unintended, catastrophic consequences, where does responsibility lie, and can blame ever truly be laid to rest? With stunning language and striking emotional intensity, A Change in Altitude illuminates the inner landscape of a couple, the irrevocable impact of tragedy and the elusive nature of forgiveness.
