This is definately a good book for someone about 10 or 11. Its got history and its also entertaining. However if you are any older than 12 I think you will find the book a little childish and a very quick read. I have noticed that the more books are published in this series the shorter and (I think) the less interesting they tend to be. The first royal diaries are the best. Still this is a good book to look at even if you only read the the historical part, so consider picking it up someday.
