As you can see from this little beauty, things were not going well in the finding books to read while camping department. This one I found at one of those book swap things they have at campsites. I think the cover is trying to let me know that this is chick lit.
There are a pair of twin sisters, one trapped in a dull marriage, one in a painful affair with a married man, who decide to change their lives. They are inspired to do so by attending the birthday party of their older and more successful sister. You will not be amazed to learn that they succeed.
It was okay, in sort of a dumb way.
