The Crust of the Earth is a lyrical novel that tells of the approaching end of the world as we know it today and the search for a new way of inhabiting the planet. Drawing on geology, painting, medicine, and the ancient arts of walking and farming, the characters weave a conversation about our civilizational crisis, machismo, and Mexico's rampant violence... And they rediscover that "the Earth is the house that contains us all: those who sow it, those who walk it, and even those who do not love it."

Before her death, Francesca Gargallo completed Mother Earth, a trilogy of novels that considers life in its biological and narrative dimensions and invites us to imagine the resumption of human civilization after the end of the world as we know it. The Crust of the Earth is the last novel in the series and connects a genre, poetry, with an Earth science: geology.

Our lives are so short that we often cannot perceive the meaning of geological time. There is no inert matter in nature. The earth is an organism in constant motion; to perceive its extremely slow dynamics, it is necessary to immerse oneself in the spirit of stone time.
