Illus. in full color. "Winter's story begins with a peg-leg sailor who aids slaves on their escape on the Underground Railroad. While working for plantation owners, Peg Leg Joe teaches the slaves a song about the drinking gourd (the Big Dipper). A couple, their son, and two others make their escape by following the song's directions. Rich paintings interpret the strong story in a clean, primitive style enhanced by bold colors. The rhythmic compositions have an energetic presence that's compelling. A fine rendering of history in picturebook format."--(starred) Booklist.
