Book Review of A Change of Altitude by Anita Shreve?

This was not my favorite book by Shreve, nor was it my least favorite. I do enjoy her books that take place in Africa because she has such a lovely command of the description of nature there. A Change of Altitude is about a couple who are temporarily living in Africa and decide to spice up their life by climbing a very challenging local mountain. They decided to pair up with some acquaintances of the husband; however the wife in that pair is a somewhat cocky and combative woman. She is easily exasperated by the main female character whom she considers to be weak and passive. During the climb a tragedy occurs and scars the main characters irrevocably. In an attempt to salvage the marriage and to heal from the trauma emotionally, the couple decides it would bring closure to attempt the climb again. The main female character evolves the most in the story and the description of the truth of mountain climbing is amazing.
