On one side of the Mason-Dixon Line lives fifteen-year-old Willow, her master's favorite servant. She's been taught to read and has learned to write. She believes her master is good to her and fears the rebel slave runaways. On the other side of the line is seventeen-year-old Cato, a black man, free born. It's his personal mission to sneak as many fugitive slaves to freedom as he can. Willow's and Cato's lives are about to intersect, with life-changing consequences for both of them. Tonya Cherie Hegamin's moving coming-of-age story is a poignant meditation on the many ways a person can be enslaved, and the force of will needed to be truly emancipated.
