Showing Come Juneteenth by Ann Rinaldi

Sis Goose is a beloved member of Luli's family, despite the fact that she was born a slave. But the family is harboring a terrible secret. And when Union soldiers arrive on their Texas plantation to announce that slaves have been declared free for nearly two years, Sis Goose is horrified to learn that the people she called family have lied to her for so long. She runs away--but her newly found freedom has tragic consequences. Includes an author's note.
