I thought this book started off quite strong with an alternative history plot line, where a meteorite hitting earth and the threat of an extinction event kickstarts the space program in the 1950s.
However I felt it went a little downhill a bit from there as we got stuck into the plot line of the discrimination women faced in the 1960s in the workplace (and their lack of place within it as equals). Which yes, is real and happened and it sucks but I guess it didn't feel quite uplifting to read at times.. Nonetheless an interesting book though.
