Joan, the main character, is an astronomer obsessed with the stars since childhood. She is content with her life as a physics professor until she sees an ad seeking the first women scientists to join NASA’s space program. While her initial attempt fails, she applies again and succeeds.
In the summer of 1980, she begins her astronaut training at Houston’s Johnson Space Center, along with other trainees, including some from the military and others chosen because of their specialist expertise. She is one of those. Some of the top military pilots are nice and some like to make jokes at the expense of women. The women know they won’t all be chosen to go to space. As a consequence one woman in particular becomes excessively competitive. Others help each other and hang out together.
The novel details the rigor of astronaut training both mentally and physically, how trainees behave under stress, and how all the stress makes some people nicer and others increasingly rude. In the midst of all this Joan continues to care for her beloved niece and discovers a love she never dreamed of in her wildest dreams.
