for Bull's Eye by Sarah N. Harvey
After Emily's aunt dies, Emily learns that everything she has always believed is a lie, and her world crumbles. Forced to face the fact that her mother is not who she thought she was, Emily tries to find the truth about her past and make sense of her future. Turning to graffiti and vandalism as a way to deal with her anger, she comes to realize that there is more to a family than shared DNA.
