After cousins Misty, Aidan, and Brooke learn to wield their ancestral power as descendants of moko healers from west Africa, they are eager to experiment with their abilities. Unfortunately, that leads Misty to unwittingly release negative, mood-altering creatures all over the family and into the Brooklyn air. But these djab are not the worst of the problems the cousins will face.

When the family visits the Benin Bronzes at the Metropolitan Museum of Art, the djab unlock an angry and determined creature from the art, and transport it back to the Brooklyn Museum. Now pieces of art are awakening and absorbing anyone close enough to snatch. It will take all the cousins’ strength, wit, and compassion as they try to stop this magic from destroying everyone in Brooklyn as it seeks satisfaction for an ancient wrong.
