Twelve-year-old Ebony-Grace Norfleet has lived with her beloved grandfather Jeremiah in Huntsville, Alabama ever since she was little. As one of the first black engineers to integrate NASA, Jeremiah has nurtured Ebony-Grace's love for all things outer space and science fiction--especially Star Wars and Star Trek. But in the summer of 1984, when trouble arises with Jeremiah, it's decided she'll spend a few weeks with her father in Harlem.
Harlem is an exciting and terrifying place for a sheltered girl from Hunstville, and Ebony-Grace's first instinct is to retreat into her imagination. But soon 126th Street begins to reveal that it has more in common with her beloved sci-fi adventures than she ever thought possible, and by summer's end, Ebony-Grace discovers that Harlem has a place for a girl whose eyes are always on the stars.
