Publishers Weekly just posted a wonderful starred review of Nothing on Earth: “MacKenzie delivers an ambitious blend of espionage thriller and metaphysical fiction that spans a decade of geopolitical upheaval . . . Anna is the consummate spy, and MacKenzie effectively narrates the story from her first-person perspective, combining her sober investigative voice with moving philosophical meditations on motherhood. The result is a gripping, complex slow burn featuring plenty of old-school tradecraft that will appeal to fans of John le Carré, Graham Greene, and Dan Fesperman.”
