Sina Vann thought she was going on a vacation to Cambodia with a friend. But she was stepping into a trap. At 13, she was sold into slavery and was trapped in a brothel, where she was raped by dozens of men almost every day for two years, and was tortured when she didn’t comply with the owners’ every wish. "When I stepped into Cambodia, my childhood ended," Vann says, "and the dark side of my life started." Vann was saved by a raid organized by anti-slavery activist Somaly Mam. She was brought to Mam’s rescue shelter, where she now works inspiring other former sex slaves to rebuild their lives. She was honored this week with a Fredrick Douglass Award from the Free the Slaves Foundation. Demi Moore and Ashton Kutcher presented her with the award.
