Science Fiction 3/5

Mathematician Elma York survives the devastation caused by a meteorite strike to the US Eastern Seaboard, and uses her skills to help a coalition of nations accelerate space colonization in the face of an anticipated climate change apocalypse. This award-winning novel has much to recommend it, including a wonderful depiction of history and an exploration of racism and mysogyny of the 1950s. I found the pacing slow, though.
