Anne Of Windy Willows, it is in the Anne Of Green Gables series. Its start is honestly: boring. However, the book does get better. It was a little bit of a let down, the other ones in the series where really good. I understand if you start it and give it up, but I got through boring bits and I enjoyed it: it gets better! I wouldn't let it stop you reading the others in the series though, they others are really good. If L. M. Montgomery was around now I would tell her to try and improve it - add a bit more action!
My words to anyone starting, or thinking about starting it are: give it a go, stick to it if you can and what is the worst that could happen? Anne of Windy Willows and Anne of Windy Poplars are the same :)
