Bonya Ahmed's life was torn apart in February when she and her husband were attacked by men with machetes on the streets of Dhaka. She was badly injured but her husband Avijit Roy died.

When she was thirteen, Ashley White took part in America's prestigious annual 'spelling Bee' competition. It involves students competing with each other in front of an audience to gain the title of the nation's best young speller. In Ashley's year a successful documentary film called Spellbound was made about the contest. Ashley was brought up by her single parent mum in a tough Washington DC neighbourhood. The film shows her as bubbly, and full of grit and determination to do the best she can. But by the time the documentary arrived in cinemas in 2002, Ashley was pregnant and homeless.
