U.S. Marshals threaten to end the journey when they demand to search the hay wagon for runaways. Can Tommy and his father keep the slaves safe and hidden? “Follow the Drinking Gourd,” a meaningful song to the slaves, is played at the beginning and during intervals throughout the story, underscoring the significance of the lyrics and music. Sound effects, including hoofbeats and a whippoorwill’s nighttime call, add dimension to this I Can Read story. Collins only slightly alters his tones to voice characters, but textual clues and book illustrations help youngsters easily identify the speakers.
