Just finished science fiction book of the year. It has everything. Three dimensional characters that grew. New premise. Lots of twists & turns. Politics. Easy flow. See the big picture on other countries. Changes in alternative history from accelerated civil rights, less violent decolonization, food riots, cold war detente, & earlier international space station with launch site moved from Florida to Brazil. Thoughtful afterword by author on why President Dewey instead of Truman to fit new premise to Hidden Figures. Worthy companion book to Hidden Figures & Mercury 13.
