Incidents in the Life of a Slave Girl 1-4

In the first four chapters of the novel it was intriguing to me how much deception there was by the slave owners. We are told all the time about the brutality and suffering of the slaves but i had no idea of how much the slave owners flatly went against their word. I thought that even when they were in a slave to master relationship that it would be necessary to keep their word. I thought another interesting part of the story was the entire tale of her grandmother, in that it always took different turns. I was completely surprised that her mistresses sister saved her and finally granted her her freedom after so many years.
