The Calculating Stars
Winner of both a Hugo, Locus and a Nebula, this book is about a mathematical prodigy battling her way into a career as an astronaut in a post-apolocalyptic 1950s America. Along the way she has to take on the embedded sexism of America in the 50s, as well as her own mild racism. Worse, she suffers from an anxiety condition. The book is engaging and well written, with an alternative history plot line which believable and interesting. In fact, its quite topical for our current time. I really enjoyed this book and I will definitely be reading the sequel.
