A postapocalyptic world, motherhood, and centaurs.

"The girls were born the day before the world ended. You had eighteen hours of bliss and then the satellites went out, and with them the systems that sent news around the world. An asteroid, you heard people say. Huddled in your darkened hospital bed, your daughter’s mouths so pink and empty. Like birds. One asteroid and then another, and another, and then so many more that no one could keep track. They pounded into the oceans and the hills. The shaking made the earthquakes come, and from them, the volcanoes. The oceans rose. The clouds that came in the wake of the asteroids were thick and hard, studded with cosmic ash."
