The first in a new magical YA fantasy duology from the author of The Girl Who Fell Beneath the Sea, set in an East Asian inspired world.

Lower your gaze. The light is not for you.

Ex-soldier Sunho lives in the Under World, a land of perpetual darkness. Possessing just his name and sword, he comes across the score of a lifetime - a chest of coins for hunting down the girl who wields silver light.

Ren is a spirited acrobat travelling with her family. But everything changes when they are attacked by a demon. Desperate, Ren releases a blast of silver light and kills the monster - but cannot save her beloved uncle from grievous injury.

Determined to save him from succumbing to the poisoned wound, Ren sets off for the mountains, where the creature came from - where Ren herself fled from ten years ago. Her path collides with Sunho's, but he doesn't realize who she is. As the two grow closer, it becomes clear their pasts - and destinies - are more entwined than they could possibly have imagined . . .
