Jamilatu Sheriff
Jamilatu, aged 21, who escaped with Fatmata from the traffickers' prison in Algeria, took a plastic bag of cash worth $3,500 from her mother's room when she was out of the house. The money didn't even belong to her mother. It had all been lent to her by neighbours, as part of a microcredit scheme.
After Jamilatu left, the furious creditors besieged her mother's house, threatening to kill her if she didn't return the money. She was forced to flee Freetown for Bo, three hours away in the south of the country, leaving her three other children behind with their father.
"My mum doesn't want to talk to me, because of the money," Jamilatu says. "So since I came back, I haven't seen her. And I want to see my mum - it's over two years now that I'm not seeing her. Jamilatu now works at Advocacy network Against irregular Migration
Fatmata Bangura
Fatmata breaks into sobs when she remembers the six months she spent in slavery as the "wife" of a Tuareg nomad who seized her in the Sahara desert.
"They call him Ahmed. He was so huge and so wicked," she says. "He said, 'You are a slave, you are black. You people are from hell.' He told me when somebody has a slave, you can do whatever you want to do. Not only him. Sometimes he would tell his friend, 'You can have a taste of anything inside my house.' They tortured me every day."
That was only the beginning of the horrors Fatmata, aged 28, from Freetown, Sierra Leone, experienced as she tried to cross West Africa to the Mediterranean. She eventually escaped from Ahmed, but was recaptured by traffickers who held her in their own private jail in Algeria.
After she and other migrants broke out, Fatmata, deeply traumatised, decided to abandon her dreams of a new life in Europe - and go back to where she started. She applied to an intergovernmental agency, the International Organization for Migration (IOM), which pays the fares for migrants who want to return home.
Last December, she arrived back in Freetown, by bus from Mali - after nearly two years away. But there were no emotional reunions, no welcomes, no embraces. Nearly a year later, Fatmata hasn't even seen her mother - or the daughter, now eight, she left behind.
"I was so happy to come back," she says. "But I wish I had not."

The IOM offers migrants who return voluntarily to their home countries in Africa "re-integration allowances" worth up to 1,500 euros (£1,270). The money comes from a 347m-euro fund financed mainly by the European Union. But the allowances aren't paid in cash. If they were, most people would just use them to repay their relatives. So the IOM pays for goods or services that applicants can prove they need to set up a specific business.
