The political and romantic tensions that began when Aislin became Summer Queen threaten to boil over as the Faerie Courts brace against the threat of all-out war.

As the price for Lucy's freedom, Soli is charged by the Faerie Queen with journeying to the Black Lake and retrieving the Dark Crown.

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.

Sixteen-year-old Evie thinks she has left the International Paranormal Containment Agency, and her own paranormal activities, behind her when she is recruited to help at the Agency, where she discovers more about the dark faerie prophecy that threatens her future.

Seventeen-year-old Leslie wants a tattoo as a way of reclaiming control of herself and her body, but the eerie image she selects pulls her into the dangerous Dark Court of the faeries, where she draws on inner strength to make a horrible choice.

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.

Lucy and the old queen are sick and dying, and Kheelan and Caro take them to the Ladybirds in hopes of a cure, while Soli remains at the castle to deal with the Crows, but the Faerieground still has many secrets and there is treachery nearby.

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.

Soli is waiting to be rescued from the Crows. Will her friends come through?
