Volcanic ash has ruined the world and only remote outposts remain. At the castle in the mountains, covered by snow, everyone only sees shades of blue.

Except for Jaisy.

By day she explores farther down the mountain. By night, she’s plagued with dreams of a panther and ghosts calling her name.

When Jaisy’s job sends her into the dungeon, she discovers a hidden room filled with dangerous information. There are secrets within the damp, stone walls that those in control don’t want anyone to know.

The leaders will kill to protect those secrets – even executing one of their own.

Jaisy will not go quietly into the blue night, no matter how hard the leaders attempt to silence her.
