Set on a planet where the only human-habitable zone is the terminus between day and night, this book is about a lot of things. It's about settler colonialism, political power, differing models of social control, the limits of political revolution, the longing for a feeling of connection to one's culture, and those weird, intense friendships between pre-teen and teen girls that make you go "is it gay? Are they on the verge of forming a cult? Or is this just a normal stage in development?"

You might enjoy this if you like LeGuin, Anne of Green Gables, or thought Enders Game could have more girls in it.
