Earthlings by Sayaka Murata

This book is pretty dark -- it tackles the question: why do we have to have kids? why do we have to go to work? Building on her earlier work "Convenience Store Woman," in which a woman lets a crazy man move in to her apartment so that people stop asking why she's single, this novel sees society as a "factory" -- either you procreate and work, or they will be out to get you!!!
