An enslaved boy, Wash, is brought on as an assistant to the plantation owner‘s brother, who is building a rudimentary hot air balloon. The novel is both deftly plotted & intensely introspective, both travelogue and fable. It‘s not a novel I loved intensely, but it did make me think, especially the ending, which defied my expectations. I‘m going to sit with it & wonder if my feeling of dissatisfaction/ambiguity is part of the novel‘s project.
