Incidents in the life of a slave girl

It wasn't easy reading this book, it describes a horrible moment in history in the lens of a slaved person, and having that kind of point of view was difficult, but important in the times we live in.
I wish I had read this book when I was younger.
In the edition I own (which is a Brazilian one) the book has an afterword, written by Jarid Arraes, that analysis the book in an incredible way, I really loved getting deeper in the review to know facts that aren't in the story itself.
