The five elements of your score:
Imagine, every single thing you do and say is scored and your future depends on your score.
This is the kind of society where Imani lives.The friends you should hang out with are the ones who have the same score as you, so you may have to say goodbye to some people along the way. Cady has been Imani's friend for a long time and they even had a pact , but when Cady's score falls ,Imani knows she should forget about her.
However, since Imani's score has also gone down, she has to do more to get a scholarship, to find a good job in the future , to be who she was meant to be .So she does what she has to do and for some good, bad and worse reasons Imani starts seeing Diego, an unscored boy, which is worse than a lowbie. And she gradually begins to see things in a different way.
Incidentally I happened to see the film The Tall Man with Jessica Biel around the time I was reading the book and the combination of both made me think about some of the positive things of being scored.
But, as you will find out there are negative things as well.
Very good food for thought.
