To Marcy's older brother's friend Steve, she has always just been "Squirt." But now she is fifteen and all grown up with a new white formal hanging in the closet, just waiting to be worn! Will Steve be able to look past the Marcy he's always known and see how she has changed? Marcy Rhodes lives in Westfield with her parents and older brother, Ken. Throughout the series, Marcy matures through meeting new people, traveling and dating a variety of boys. The series has a warm and happy feeling of the 1950s.

Marcy Rhodes thought that when she turned seventeen "things would be different." She is suddenly whirled into a delightful summer in which things really do change. A visit to a ranch in Colorado, the thrill of meeting new and interesting boys, and a serious romantic involvement give Marcy a truly different outlook and the ability to make a very important decision...

In her senior year in high school, Marcy's steady date, Steve, departs for his freshman year at college. Marcy and some friends in a similar plight form the "Widow's Club." Many of the girls drop out, but Marcy is determined to stay true to Steve...until jealousy threatens to destroy their relationship. Some sound advice from Marcy's brother, Ken, and some straightforward thinking by Marcy herself help her find a fresh new approach to the year of "widowhood."

The climax of Marcy's last year in high school was destined to be the Senior Prom. From Christmas vacation on it was a busy and happy time for Marcy. There was her appointment as feature editor of the school paper, her regular chess games with sweet old Mr. Tuttle, and an exciting trip to Washington and New York. Perhaps most notably was the problem of Bruce and Rick. Bruce, with his yellow convertible and his charm, his humor and good looks....Rick, reliable, unselfish, and attractive, but shy and unable to dance...and Senior Prom a few weeks off!
