To Be a Slave - Can we trust?

Yes i think it is OK to trust the book To Be a Slave, because the author's ancestors were slaves, and he might know well what it is to be a slave and how they became slaves. Also, the book is very realistic and it is possible that similar things happened in the book. He also wrote this book using other reliable sources related to the slaves. And also by looking at his academic background, he is a professor in a famous university in U.S, teaching african studies.
