When Rani Hong was just seven years old she was taken from her family in India and sold into slavery. At an age when she should have been playing with dolls and making new friends at school, she was subjected to treatment that left her close to death.

"I was transported to another state, where I did not speak the language, I was disoriented. I was afraid, and alone, crying for my mom to come get me," she recalled to CNN. "My captors used intimidation and force to control me."

Eventually she became so sick she was of little use to her "slave master" and was sold into illegal adoption in the United States, where she rebuilt her life.

On International Day of the Girl, Hong -- who as an adult has devoted her life to fighting slavery -- joined a live Twitter chat to discuss how we can all do our part to end slavery.

Here are excerpts from the chat, where Hong, survivors, anti-slavery NGOs and others share their advice on how we can help.
