I’m sure that Fiction stories existed at the time and much of fiction is based on our experience in the real world.
I’m sure that the attitude of the slaves themselves in the books were dependent on the author and their background, but what are some examples from the time?
/u/EdHistory101 (under a previous alias) has previously answered Was there any literature for slaveowners in the American South in the pre-Civil War 1800s that would tell them how to best own a slave or run a slave plantation? A "Slavery Daily" or somesuch?
/u/chalantcop has previously answered How did minstrel shows, and the use of blackface, develop in American theater?
There are many other answers to this question waiting to be written.
EDIT: There were also tropes associated with slave narratives for an abolitionist audience described by a user who does not want to be pinged anymore. Another answer about the testimony of Wesley Norris
