Seveneves by Book*Sense

After a catastrophic event shreds the Moon into a deadly cascade of debris that will render Earth uninhabitable, humanity scrambles to preserve itself by building an ark in orbit. Political chaos, engineering feats and genetic triage follow as a small group of women become the genetic founders of the future human race, while generations later their descendants confront the social, technological and evolutionary consequences as they return to a radically changed Earth. The story blends hard science, long-term speculation and human drama to examine survival, identity and the costs of remaking humanity.
