Experimental Design Book

I think this was the 18th Human Trafficking book I've read. What I liked about this one that stood out from all the others, is we get a few stories from actual slaves from all different viewpoints, yet about three were live-in-maids (in which one is a child), which I hadn't really read many accounts of before in the past. We also get to hear about a labor camp prisoner survivor and a man who lived in a family that owned slaves but became an abolitionist. Most books I've read focus on the sexual exploitation part of slavery (which is indeed cruel and disgusting) but this book really had only one story like that which was a horrific account from a girl who was a sex slave from age 14-17 in the early 1980s. It was a very good book and didn't give you statistics or try to convince and educate you, but just gave you real life accounts. This was unique and I am glad I finally read it after wanting to for three years!!!
