Lucy is a prisoner in the Faerieground, and Soli must take the silver necklace that Lucy's mother has given her and venture into the Willow Forest if she is to rescue her best friend.

Lucy and Soli are reunited and learn the secrets of Faerieground, the Queen, and their own identities.

The Crows offer Faerie princess Soli a choice between saving her lifelong friend Lucy or her mother, but treachery is present whatever she chooses.

Although Soledad and Lucy are returning to the human world to see their families, their work in the Faerieground is not finished--war threatens and Soli is a faerie princess, so her future lies there.

As Lucy, Kheelan, and the united Faerie march to war against the Crows, Soli discovers who has been smuggling Kheelan's messages to her, and learns Caro's secret--and Lucy's mother returns to the Faerieground.

Soli is still in the kingdom of the Crows, who want to turn her into one of them--meanwhile the other six kingdoms are choosing whether to unite against the Crows, and Lucy has learned that her own mother, back in the world, could bring ruin if she crosses over to Faerieground.
