Kem Luther

In atmospheric science, a boundary layer is where the ground comes into contact with the air. In the Pacific Northwest, this boundary layer teems with lichens, mosses, ferns, fungi, and diminutive plants. It’s a universe in miniature, an unexplored territory that author Kem Luther calls the stegnon, the terrestrial equivalent of oceanic plankton. In Boundary Layer, Luther takes a voyage of discovery through the stegnon, exploring the life forms that thrive there and introducing readers to the scientists who study them.
