I am finally getting around to comment on the Royal Diary series. I’ve only read a few of them. I wouldn’t classify them as great literature but they made good reading. I did learn a few things from the historical stand point. Each one was written by a different author and I would recommend someone reading through each book before it goes on the school shelf. Our school library standard isn’t too stringent but they may not fit on everyone’s shelf. A co-teacher did comment about one of the books that is not in our library. She owns the book and wasn’t sure it was a book that she wanted her younger brothers to read. I didn’t read the book so I don’t exactly know why she made that comment. I think it was one of the queens of England but I don’t know for sure which one. I would say these books are similar to the American Diary series.
