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.

Mister Fairy spreads happiness and joy wherever he goes.

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.

Moose wants to be a fairy, so he joins the Secret Fairy Club. But he soon discovers that all the other fairies are... well, little! As fabulous a fairy as Moose is, the other club members feel he is too big and too different to fit in. Will they change their mind after Moose comes to the rescue?

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.
