Rated of 5
I have experienced both books by Ms. Greenlaw. The 1st by audio tape and the second by reading. The 1st is more adventurous and entices you to read the 2nd one. The 2nd pulls you more into the experience of a struggling human being and you end up wanting to read a 3rd to see what happens (while hoping for a happy ending). The book doesn't end, it pauses.
It is entertaining and educational. Most of all it is an exposition of the struggles of life in work and the family. This is really reality; it's as though leisure time doesn't exist.
If I had to bet, I would not take the happy ending option. But I would bet the house that no matter what happens, Ms. Greenlaw is going to give it her best shot and be ready for more.
I would cast Katherine Hepburn for the movie version.
