I haven't read these but I know any child who loves mysteries and reading will love them. I would love to have the entire series in my classroom. This would be a fun book report project or a book for a student to read and then share about it to the class. I would use this for a read to self idea with 3-5 grade. That way if another student hears about the book and they would like to read it they know the background story behind it.
