A week in paradise is never enough. It beckons us back again and again. Cooper describes a week in such a place. We feel the struggles of the characters as they move through the week toward resolution in dealing with their lives.
We probably all have such places even if it's not on a Mexican beach. I know my own Room of Love that is capable of transforming one's life while making meaningful connections. We all never want to leave but at some point we must, yearning to return before we've reached our default lives.
