This is the tenth book in the Thea Stilton series. This book takes the Thea Sisters to Scotland to help out a friend and her family with the family's castle and what is supposed to happen to it now. Will the Thea Sisters be able to find their friend in time before the family meeting?

This was a very interesting book about the history of Scotland. Lots of very interesting facts about the country and the culture. Great read.

A book chosen by my daughter. I liked the story because it provides information about another culture. It shows how friends can come together to help each other. It had a mystery in it and good ending.
