The Bell Bandit from the series The Lemonade War and The Lemonade Crime by Jacqueline Davies
This is the most recent book that has come out in this series. This was an easy book for me because I did read this at the end of fourth grade. I am an advanced reader so this may be just right for some other kids. This could also be an easy read like I did. You could also read this in the beginning of fourth grade for future fourth graders.
The Hunger Games series by Suzanne Collins
The Hunger Games is a book that many people say is inappropriate for young people, but let someone who is a young fourth grader tell you. Let me tell you this if you can separate the difference from real and from imaginary your okay. If you will have nightmares from a scary movie then you are in trouble. It might be okay if you talk about to your adult but it might be hard for you to get the sad image out of your head. I am a fourth grader going into fifth grade and read the whole series and my friends did to and it was perfectly okay for all of us. I also watched the movie I read the book okay. There was a younger girl my friend how was only in third grade and I felt uncomfortable for her to see the movie also having her not reading the book. So I would recommend this book to fourth graders no younger than that but maybe better if you were older but fourth grade is okay too. Read the book first then watch the movie. Like always the book better but the movie was really good. You have to read the books in order because they will not make any sense if you read them out-of-order.
