A picture book biography of Dr. Kathy Sullivan. The book goes back and forth between Kathy as a child and as an adult. The pages written as an adult have text in italics. The text is simple and written as a story. Kathy dreamed of having adventures and she loved maps, books, and foreign languages. She thought she might grow up to be a spy or diplomat, but most people told her those were not jobs for girls. She learned to be a pilot as a teenager.

The end of the book gives more details about Kathy, as well as mini biographies of fourteen other women astronauts.
