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.

Win “Coal” Keegan has just landed in his latest foster home, with a big, noisy, slightly nosy family named the McKays. They seem eager to welcome Coal, but he’s wary of trusting them. So, he doesn’t tell them that he went for a walk with chalk in his pocket to cover a nearby street with his art. He doesn’t tell them that a neighbor found Coal drawing, pulled a gun on him, and fired it. He doesn’t tell them the police chased him. And he definitely doesn’t tell them that when everything went down, Coal somehow turned invisible.

But he did.

Now he has to figure out how. Is he a superhero? Some kind of mutant? A science experiment? Is that why he has no family of his own? As Coal searches for answers and slowly learns to control his invisibility, he turns to the McKay kids and friends both new and old for help. But they soon discover they’re not the only ones looking for a Black boy with superpowers, and the situation is far stranger—and more dangerous—than they ever could have expected.

Cousins Misty, Aidan, and Brooke discover that they carry the ancestral power of real moko healers from west Africa, and are the descendants of the first moko jumbie who followed a slave ship across the Atlantic ocean. The revelation comes with new magical abilities: Misty can see into the past and the future. Aidan can heal with a touch. Brooke can project force fields to protect.

They also learn that their community is filled with the descendants of other magical beings with extraordinary abilities like flying, granting wishes, or making food that can cause temporary super powers. The cousins must protect them all. But a series of mysterious attacks that drains magic threatens the community. In the lead-up to the Caribbean Day Parade on Eastern Parkway when all magical beings will be gathered, the attacks grow worse. The cousins need to quickly learn to control their abilities, figure out how to get along, and stop the attacks before all the magic is gone.
