"Alissa"

I read this book called Alissa.
Alissa is 12 years old and loves to read. One day fat guy came to her house and took her to the cloth shop to work there. She worked so hard, but the owner payed a little.
One day, the tall and pretty lady came to the shop and left her purse in the shop. Alissa run after the lady and gave back to her. When she backed to the shop, the owner was so mad to her that she left the shop. She cried and suddenlly the tall lady came in and took her. She said "you are living with me." Now she can lives happy and go to school.

I was surprised that Alissa had to work so hard even she was only twelve! That's so sad. I wonder are there still some people treated as slaves? I guess there isn't in Japan…but I don't know.
