I have been reading these books for months and my mum told meat pick up from school that her friend was moving to the U.S. and she gave me these books for me. In there was the whole of the Nancy drew series. I was so thankful and there was a load of other books. The books are all about a girl who finds something and finds out that it is very valuable and she keeps it for years and years. There is a mystery in every book. It is very interesting because you can imagine what it would be like to be in that situation. I recommend these books for people who like mystery stories.
