Unlike other books about the Challenger disaster that exclusively focus on the incident, this is a respectful biographical account of one of the non-astronauts on board. Using a plethora of primary and secondary sources, including personal interviews and shuttle operation manuals, Cook puts together the story of McAuliffe’s life, why she wanted to go into space, and what happened after the incident. While Cook does offer details on the disaster and the commission to investigate it, the book’s primary focus is the crew members and their families, which personalizes a pivotal moment in the history of NASA, space exploration, and the U.S..
