West of January — Dave Duncan

Set on a distant planet, far in the future, West of January tells the story of a world in which time moves very slowly. Because it takes a lifetime for each region of the planet to experience dawn, midday and dusk, the planet's population does not remember the catastrophes that occur as the sun moves across the sky-entire civilizations have been scorched into oblivion. The only people who remember the dangers of the past are the planet's angels-a people who have tried to preserve past technologies to save the planet. This action-filled story of a very strange planet showcases Duncan's remarkable ability to create unique worlds.
