When 11-year-old Dmitri ("D") loses his mother to breast cancer, he finds himself taken in by an elderly white woman, Mrs. Martin. D loves to watch birds and, while in the park, is amazed to find an injured bird that can talk. He takes it home and soon learns there are malevolent forces inhabiting the region beneath Prospect Park and they are hunting for the bird; Nuru is a life force that has been kept hostage by the earthbound spirits who are ghosts of soldiers that died in the Revolutionary War. Nuru's mission is to guide the ship that will carry the souls of the dead back to her realm. D has been chosen as Nuru's host, and must carry the bird from Brooklyn to the African Burial Ground in lower Manhattan where the dead await deliverance.
