I think that perhaps this book could appeal to some adults who have been diagnosed with a terminal illness. Having already lived some of the life experiences Tessa has on her list, might encourage one to think about their remaining days and make a list of their own. While I found some of the experiences on the list, things I didn't like, it is her list. The end of the book is beautifully written. I shall give this book to my two granddaughters who are 13 and 16. It will be interesting to hear their comments.
