I just read this really moving book called 'Freedom' by Mende Nazer. It is the sequel to 'Slave', which I read a few years ago, about a girl who was sold into slavery. The sequel tells the story of how she travels back to the Sudan to find the family she lost. Makes you appreciate your easy life in the West! Seriously, worth a read.
