Dang, that Dune II trailer looks good.
I don't often put movies on my "watch" list several months in advance (or go to see them at all), but for this one, I'll make an exception.
Speaking of movies and books, while I haven't seen Sound of Freedom yet, I have had the chance to meet some people in that line of work (liberating sex slaves), and do have a few good books to recommend:
Julia Siler, The White Devil's Daughters: The Women Who Fought Slavery in San Francisco's Chinatown. This is about Presbyterian and Methodist missionaries around the turn of the previous century, who rescued thousands of Asian girls from the trade. Like Herodotus, the author is wise enough to jump around a bit, from interesting story to interesting story. (Female or male, San Francisco or, in one interesting case, Seattle.) Her perspective appears to be modern "progressive," with emphasis on modern moral shibboleths, rather than Christian per se, so one misses the interior perspective of the agents of liberation some, though Siler recognizes and credits their motivation from the outside. (And for all I know, could be a Christian herself, hiding it carefully.)
Gary Haugen, Good News About Injustice. This book sounds closest in spirit to the new movie. Haugen was a lawyer in civil rights before becoming CEO of International Justice Mission, and trying to save kids through means legal and dangerous. Despite the title, the book is rather depressing, but important.
Jackie Pullinger, Chasing the Dragon. Much more "spiritual" and inspiring, mostly about freeing gangsters from drug addictions, but some trafficked women also come into it. As does God, in a big way.
