One possible theme could be self - identity. As a girl grows up, she often has to figure out who she is, especially in a true story where real - life experiences shape her sense of self.
Since we don't know who this 'girl like her' is, it's impossible to accurately state her true story. There are countless girls out there, each with a unique set of experiences. It could be a story of love, friendship, or self - discovery. However, without proper identification, we can't really go into details about her story.
One book could be 'The Glass Castle'. It's a memoir that shares a true story of a girl growing up in difficult circumstances, much like 'A Girl Like Me True Story' might do. It shows her journey of self - discovery and survival.
