They taught us to fear the Darkness. They never taught us why. For generations, humanity has survived beneath the glow of colossal Lighthouses while the Lantern Runners risk their lives beyond the walls to keep the abyss at bay. Gabriel has always dreamed of joining them. But when an encounter with the Darkness leaves him questioning everything he thought he knew, he is drawn into a mystery older than the cities themselves-a mystery that could change humanity's future forever. Because some truths are buried for a reason. And sometimes... the greatest threat isn't what waits beyond the light. It's what has been hidden within it.
