Michelle and Debra begins when Michelle and her best friend, Debra, are thirteen and enjoying the activities of girls camp. Michelle, a faithful young woman, tries to encourage and influence Debra to make more responsible decisions. Debra, however, does not place as much importance on the gospel and never makes a full commitment to abstain from immoral behavior. The chapters about the two girls alternate with the story of Shane,who grows up in Montana and prepares for a mission and returns while the girls are progressing through high school in Utah. The decisions that Michelle, Debra, and Shane make determine the results that come from keeping or breaking their commitments. In the story, a beautiful temple wedding illustrates the blessings that can be rewarded to those who live up to their commitments.
