Fiction by Ann Leary.
The main character of this book is the wife of a Big Hollywood Star. It's an interesting perspective, and one I'd never really thought about.
Think about this:
What if your husband, the man who farts in his sleep and leaves toothpaste blobs hardening in the sink for you to chip off later, is the nation's heart-throb? I mean, even Brad Pitt isn't awesome twenty-four/seven. But I'll bet everyone treats him like he is.
