Part thrilling sci-fi adventure, part historical fiction, Earth’s Harmony is an endlessly imaginative tale from the creative mind of debut author Geoffrey Currens. In the near future, perhaps tomorrow, humanity receives a message from deep space in an alien language—a distress call, along with a set of blueprints. Two generations later, Earth is growing increasingly barren; animals are becoming scarce, and lakes are drying up. Nonetheless, as the distress called warned, alien attackers arrive at Earth seeking the one resource remaining worth harvesting: human slaves. Due in no small part to the efforts of pilot Byron “Cowboy” Carruthers and his ace gunner, Jim, the alien attack is fought off, but one ship manages to escape through a vortex into the past, where the alien could potentially take over the Earth and bring about a horrific future. Cowboy and Jim must pursue the alien through the vortex aboard the result of the blueprints received in the distress call so long ago—a telepathic ship they name “Mother.” Cowboy and Jim thus end up in the Devil’s Lake area of North Dakota in 1889, where awaiting them is the harsh prairie winter, an Indigenous man named Dreamwalker whose knowledge and collection of animals may prove pivotal to their mission, and a romance that will test Cowboy’s resolve to not make any ripples in time. Can they stop the alien—and their own actions—from destroying Earth’s chance at a future?
