There is a kingdom called Demeter where light is worshipped and shadows are feared. In this kingdom lives a princess named Nell, eighteen years old, who carries a secret that could destroy her: she possesses shadow magic, the very thing her people have been taught to revile. She has spent her life hiding this truth, binding herself into corsets, avoiding mirrors, and pretending to be something she is not. The novel opens on the eve of her birthday, but this is no ordinary celebration. Years ago, when Nell's mother lay dying, her father made a desperate bargain with the Shadow King of Faerie. The price was not gold or land or political favor. The price was Nell herself.

The love story at the heart of this book is tangled with curses, bargains, and a betrayal that cuts deeper than any blade. The central question the story explores is one of identity and sacrifice. What does it mean to give yourself to someone else? What parts of you survive when you are broken apart? And…
