What it's about

In 1952 a huge meteorite strikes the Atlantic off Washington, D.C., destroying much of the East Coast. Elma York, a mathematician and former wartime pilot, calculates that the climate will soon make Earth unlivable, and humanity must get to space far faster than planned. She works as a 'computer' for the new space program and sets her heart on becoming an astronaut, while the men in charge insist women can't.

Why it's worth reading

It won the Hugo, the Nebula and the Locus awards. It's an alternate history of the space race, full of math, flying and fighting for a place.

Good to know

Elma's anxiety disorder is a big part of the story, as are sexism and racism in the 1950s. There are frank sex scenes within her marriage.
