My book: Chinese Cinderella by Adeline Yen Mah
Adeline is in kindergarten in China and she does very well in school and gets many awards for that. Her mom died while giving birth to her so her whole family treats her really bad and they blame her. She now has a stepmother named Niang since she was 1 years old. She lives in a French part of town and goes to a French school. She really likes school because she feels like she belongs there. One day her father goes missing, two weeks later Niang and her son also go missing. Adeline's grandma Nai Nai then dies from a stroke and there is a funeral held for her. All of the family is then taken by train to Shanghai, and they found out that Father and Niang have been living there and have a house there. Adeline goes to school and when school is over, nobody comes to pick her up, so she has to wander the streets of Shanghai trying to get home. She is only in first grade now. She finally remembered her new phone number so she was able to call her father to come and get her. Nobody really watches after Adeline but her Aunt Baba.
I think that it would be hard to keep track of adeline, because there are a total of 7 kids in their family. However they purposely don't take care of her because they blame her for the mother dying which is really sad. Eventually, i think that Adeline (who is also called fifth daughter) will learn to take care of herself.
