Cause Celeb Book

I can't understand why this only averages a rating of 3! This is definitely very different from the Bridget Jones series, but the author's vivid descriptions of Africa alone made me want to jump on a plane. The scene where the massive wave of famine victims were cresting the hill will live in my mind for the rest of my life.
In Cause Celeb, a bunch of shallow actors were milking the media attention from a famine relief campaign but got the education of their lives when they were confronted with mass starvation on such a huge scale. This was Helen Fielding at her most sincere, and the writing was excellent: it was not preachy, but it did make me examine my own entitled life. Perhaps the low rating reflects some form of disappointment from readers who were expecting more of the same light fare that we came to expect in the Bridget series?
Oh well, we readers do tend to pigeon-hole authors sometimes, and can balk at allowing an author any artistic freedom.
I, for one, was so impressed with this story about a shallow young woman who takes off for Africa after a messy break up. Rosie not only finds her true self in her bumbling efforts to provide aid where it was so desperately needed, she discovers her life's vocation. Rosie's outlook on life was forever changed by her experience as a relief worker. A five star rating for me for excellent character development and storytelling!
