Our Narrow Sky

Eight thousand people live beneath the Pacific Ocean, convinced the surface world is dead. Georgia Muller dives the colony's hull for a living, patching fractures in the only home humanity supposedly has left—until she finds a steel cable stretching upward into the dark water, taut and anchored to something that shouldn't exist. Her discovery triggers a reassignment meant to silence her, but Georgia has never been good at staying quiet. What she uncovers next will shatter everything the colony believes about survival, freedom, and the sky they were told they'd never see again.
