Q: Excellent book. I've read all but a few pages. I was very touched by Mr Bok's description of his childhood as a slave. A few years ago I'd heard that the Sudan had some problems; after reading this book I have a little idea of those problems in general and of slavery in particular. I strongly recommend this book.
A:
Positive
