Title: Girl Inside
First published: September 1, 1984
Description: THE TIME WAS RIPE!

Becca had always been ready to eat. As a child, eager to please her mother, she had cleaned her plate, even asked for seconds. Later, it was cookies and milk, pizza and French fries, ice cream and fudge sauce. Now it was all catching up with her. Nobody cared what a good person she was. Nobody noticed how smart she was. The slim, petite girls were chosen for the school honors and all the boys ran after them. 

She had just about given up when a sudden impulse led to an exciting new job. For the first time in years, she began to regain her self-respect and, in the process, improved her love life beyond her wildest dreams. [text from book jacket]
