DescriptionOnly a Time Machine is a collection of essays exploring issues of gender, science, motherhood, personal fulfillment, and identity. These essays put readers into the steel-toed boots of a nineteen-year-old woman working on an offshore natural gas platform, taking them with her on a thirty-year journey that ends in a very different pair of boots—the groovy go-go boots of a Star Trek science officer. Their author, Mary Anna Evans, is a licensed chemical engineer, an awardwinning novelist, and a very proud mother.
