I will never reread this because I would probably hate it, but GOD did I love this story when I was a kid. I read it before I read the first Heidi book, and I think that ruined my enjoyment of the first. I adore this book, even though it's basically fanfiction, and I love finding out what happened to all the characters I loved the first time round. I laughed, I cried, I cheered when Peter and Heidi finally get married.
It's not great writing, but I don't even care.
