An end-of-the-world love story, an epic full of pathos and humor, asking what can be saved of our planet Well, that’s about it for the story of planet Earth, poor Earth, reduced to not much more than a piece of burnt coal. But, as Deb Olin Unferth shows in her latest electrifying novel, life and love persist, even in the most unexpected, inhospitable places. Two women meet on a beach of artificial sand. One was raised in a pod in the ocean and the other may or may not be a robot. Their love—or any love—seems so unlikely. Earth is severely depopulated. Some people have given up, gone off to Mars. Others pursue eternal life as digital code. And yet others, like Dylan and Melanie, are holdouts—and some of those holdouts are constructing a vast molecular collection in hopes that a future person may be alive to make a new Earth. Foolhardy? Misguided? Quixotic? Probably. But what can a human (or a robot) do? By the end of Unferth’s wild, poetic, revelatory, and slyly philosophical novel, the reader has traveled to the very edges of the cosmos as a “soul globule” and between grains of sand as a microscopic tardigrade. A slim book tackling big questions (is all matter conscious? will we tech ourselves into salvation, or out of existence?), Earth 7 is a poignant inquiry into death, mourning, and indefatigable life, the most exhilarating work to date by one of our most original and beloved writers.
