If you are not planning a trip to Scotland this is not a book you will find interesting. There are 133 sites listed on 86 pages so there isn't much detail and the ghost stories are very limited. If you are going to Scotland however, this book will give you a good start to planning your itinerary if you like to visit haunted sites.
For each site listed there is a short history of the castle and sometimes a short history of the ghost or ghosts. Sometimes though the history of the haunting is much too brief. In fact, sometimes the whole haunting is taken care of in one sentence. This is one aspect of the book I didn't care for. I was also put off by there being lots of information about the facilities at some sites while no mention was made of visitor infomation at other sites. Some of these castles are private and people still live there and on some occasions that is mentioned but a lot of the time there is NO visitor info or details about visitors being welcome or not.
Just a little more information would have made this a much better book. Still it was worth the price and it did travel to Scotland with me.
