The Edge of Night

The apocalypse ended years ago. From the carnage of war, rival societies influenced by misunderstanding have sought refuge in the sky above Earth's devastated surface. Having grown up in constant sunlight, never seeing traces of night, Sage, a daylighter, wonders why his dad is scared of the dark. Years later after a violent solar storm cripples his skyjammer, he briefly encounters exiles from Earth's dark side. When captured by nightdwellers, people who live only in the darkness, he's held prisoner in an unimaginable place. Sage learns why his father was afraid, as escape may be futile from those who lurk on the edge of night.
