Lauren Stienstra explores a world redefined by a shocking revelation: there is a biological countdown to extinction encoded into every living creature's DNA. For humanity, just four generations remain. How and when people choose to reproduce takes center stage. Stienstra draws on extensive experience in science, public health, and crisis management, to create a robustly-imagined world that is rich with ethical quandaries. She holds degrees in physiology and crisis management, has studied creative writing at UCLA Extension, and is currently completing her doctorate in public health at Johns Hopkins University.
