Station Eleven by Emily St. John Mandel is about the world after a pandemic kills the majority of humans.
Beginning in the last days of the current civilization, then jumping a few years into the future, we see how life has changed for the survivors.
Kristen was a young girl when the plague happened. She was already drawn to acting, so her membership in the Traveling Symphony years later is no surprise. The group of actors and musicians travel along the edge of Lake Michigan, stopping in the towns to perform, trade news and supplies, and provide a break from the new normal for the town folks.
This is all I will say about the details. This is one of the best post-apocalyptic stories I have read. Mandel does not shy away from the dark parts of the change, but also does not gratuitously explain each gory detail. In fact, the plague was so fast and efficient, it is over quickly.
Read the book before you watch the HBO series based on the book.
