What is the Main idea of dust by Charles Garyson

Personally I think the theme would be have to be:  Find the best in what you have.

Explanation:

I read up on some things about this book for you and it seems that is the leading theme.  

it is the background information on the characters and setting explained at the beginning of the story. the exposition will often have information about events that happened before the story began. the exposition is often the very first part of the plot.

from the political point of view it could be said that the candidate   is an effective speaker because she takes a strong position on the issue. it is an open discussion but probably she is making a presentation and can choose which subjects she wants to address. she is very likely to attain her aim which is to convince voters to accept her proposal.
