This book is SO unique. It is the "Jungle Book" only set in a grave yard. I read it with my 9 year old. A really fun special thing to do with this book is to watch/listen to the author read it online because Neil Gaiman read one chapter at each publicity stop on his tour for this book so if you go to his website you can watch him read the entire book. He's very emotive and a wonderful to listen to.
As we read the book we discussed issues that would come up--bravery, moving out on your own when you are grown, why the ghosts had different views of life (because of how much customs changed from when the different ghosts were alive), etc. This is a very engrossing fun book to read for the adventrue of the story but it also encourages imagination because it is so unique a take on what *can* happen. It was fun to have my daughter talk about "what if ..." afterward and make up little short stories of her own.
There is some violence right off. However, it is not described merely you are told that it happens. So, it is left to the reader's imagination to fill in how bloody or horrible the scene is. (Which I prefer, excessive description is unnecessary.)
