A Change in Altitude by Anita Shreve

I have ready all of Shreve's novels and have loved every one of them. She never uses a formula in her writing. Every book is totally different. In this book we follow a few years in the life of Margaret and Patrick. They have only been married for a few months when they take advantage of a chance to go to Kenya so that Patrick can practice equatorial medicine. There are some adjustments to the culture but mostly things are going well. Then a British couple invites then to climb Mount Kenya. Now keep in mind that these people are not climbers but they still say yes. During the climb there is a tragic accident and someone dies. The rest of the story is about how that incident on the mountain affects their lives and their marriage. I loved it.
