The day Grace is called from the slave cabins to work in the Big House, Mama makes her promise to keep her eyes down. Uncle Jim warns her to keep her thoughts tucked private in her mind or they could bring a whole lot of trouble and pain. But the more Grace sees of the heartless Master and hateful Missus, the more a rightiness voice clamors in her head-asking how come white folks can own other people, sell them on the auction block, and separate families forever. When that voice escapes without warning, it sets off a terrible chain of events that prove Uncle Jim's words true. Suddenly, Grace and her family must flee deep into the woods, where they brave deadly animals, slave patrollers, and the uncertainty of ever finding freedom. With candor and compassion, Ann E. Burg sheds light on a startling chapter of American history--the remarkable story of runaways who sought sanctuary in the Great Dismal Swamp--and creates a powerful testament to the right of every human to be free.
