On his deathbed, Conall's father makes him promise to always take care of his little sister, Lainn. With her laughter, she can sing the bees from their hives and make the morning sun sparkle in the winter. He loves Lainn with all his heart, and will do anything to protect her, even without a promise to his father.

He failed.

Between an abusive step-father, a powerful Faerie Queen, and a maddened Fae Lord, every decision Conall makes seems to be the wrong one. Starvation, imprisonment, madness, and disfigurement plagues them. Even when he tries following his heart, it turns to disaster.

Can Conall correct his mistakes and save Lainn's life and soul?

Will it cost him his own?
