In rural Transylvania, a castle called Piscul Dracului has been regarded with wonder and fear since stories emerged of people disappearing into the wildwood that surrounds its grounds. For Jena, her four sisters and their father, the castle has been a place of happy memories and occasional sadness. Piscul Dracului also holds a surprising secret: every Full Moon the girls cross into the Other Kingdom through a secret portal. There they visit the Dancing Glade, where a wondrous celebration is lead by Ileana, queen of the forest people, and her consort, Marin. With their numerous and diverse friends, they dance through the night until dawn when they must cross over the Bright Between and go back to their daily routine.
