The author of this book is Rosemary Wells. She wrote the Max & Ruby stories, which I used to like.
Following Grandfather is about the love and friendship between a mouse and her grandfather. It is also about how you feel when somebody who you love dies. In this book, the mice act like people. The grandfather even had a restaurant for mice.
Some of this book was a little challenging for me so my mom helped me with it. It takes place in and near Boston so kids in this area may especially like it.
