Broken Moon by Kim Antieau
Nadira lives in either Pakistan or India where the reality for young, poor people is very harsh. She has been scarred as revenge for something her brother was accused of but didn't do. She believes no one will ever love her because of the scar on her face. Her brother is kidnapped (or sold) to become a camel jockey in another land. Nadira dresses as a boy to find him and bring him home. Life for the camel jockeys is very hard and dangerous, but through her telling of the stories of Shahrazad, she is able to survive and find her brother and bring him home.
This story reminded me a lot of Sold by Patricia McCormick. It depicts the harshness but also the hope. I give it a YAY
