It's the 1850s and enslaved siblings Jeb and Mattie are about the make a break for freedom. The pair travel north from Maryland to New Bedford, Massachusetts along the Underground Railroad. Each spread tells about a step of their journey through a poem in the first person perspective. The main and repeating voices are Jeb and Mattie, but we also hear from the stationmasters and conductors, those who offer them haven, as well as those who want to capture them. Like its predecessors in the Voices series, this richly researched and beautifully illustrated picture book brings a difficult chapter of American history to life for young readers.
