How does the author use symbolism in the novel, The Underground Railroad?

Throughout the narrative, fire and its after-effects are representative of the destructive side of racist attitudes. Stations on the underground railroad are burned down; the Valentine farm in Indiana, a populous refuge for escaped slaves, is likely burned down; and after she has been captured by slave catcher Ridgeway, Cora travels through an area of Tennessee that has been destroyed by fire. For further consideration of this aspect of her journey, see "The Burned Lands" below.
