Calculating the Stars by Mary Robinette Kowal

I absolutely adored the The Lady Astronaut  of Mars byMary Robinette Kowal, featuring the same lead character as this book. I kept waiting for this Elma to grow into that one-- and undoubtedly she will, though it will be in the period between the end of this book and the beginning of the novella. Either way, there still was a lot to enjoy about this story, and the premise has given me lots to think about-- a meteorite strikes the east coast of the US in 1952, wiping out cities and lives, setting the world up for drastic climate change. It also causes drastic changes in the timeline for the US Space program.

Things I liked about this book: the relationship the two Drs York have, both the playfulness, and the support they give each other, how Elma's eyes are slowly opened to the inequality to those Americans not fortunate enough to be born white or male, the friendships that existed and the strength many of the characters showed. Yes, this is an alternative history, and the science behind that "what if" is fascinating, but like Kowal's other books, it is the relationships between the characters that drives the story.

I did listen to the audio version, read by the author, and I admit to willing suspension of disbelief when she tried to do what she thought would be a Charleston accent speaking Yiddish or Hebrew.

From the publisher:
A meteor decimates the U.S. government and paves the way for a climate cataclysm that will eventually render the earth inhospitable to humanity. This looming threat calls for a radically accelerated timeline in the earth’s efforts to colonize space, as well as an unprecedented opportunity for a much larger share of humanity to take part.

One of these new entrants in the space race is Elma York, whose experience as a WASP pilot and mathematician earns her a place in the International Aerospace Coalition’s attempts to put man on the moon. But with so many skilled and experienced women pilots and scientists involved with the program, it doesn’t take long before Elma begins to wonder why they can’t go into space, too—aside from some pesky barriers like thousands of years of history and a host of expectations about the proper place of the fairer sex. And yet, Elma’s drive to become the first Lady Astronaut is so strong that even the most dearly held conventions may not stand a chance.
