Don't you dare read this Mrs Dunphrey

My book is called don't you dare read this Mrs Dunphrey, the author is named Margaret Peterson haddix. My book is about a student who has to write in a journal because it's her assignment for the year. She starts writing in her journal more private stuff like her personal things that is happening in the family. The theme of my book is that if you keep silent the things happening in your life would get worse so you have to tell someone what's going on if it's bad. "The reason I'm doing this is, I realized I have to tell someone about mom and dad leaving us. I thought I could take care of everything myself but I just can't." Page 114. She kept quiet and it got kind of harder for her, so she finally told someone. It was her teacher, so the teacher tells the officials and they investigate.
