8Each of us has a "silent thunder" - a quiet desire that rumbles from deep-down. For eleven-year-old Summer and her older brother Rosco, their secret dreams seem far out of reach. Both are slaves on a Virginia plantation in the year 1862. More than anything, Summer wants to learn to read and write. Rosco is eager to join the Union Army so that he can fight for the cause that would allow all people to be free. Told in alternating voices, this is a work of historical fiction by bestselling and award-winning author Andrea Davis Pinkney.
