Like many other readers I had this book over and over from the library when I was growing up. Some 40 years later I got myself a copy (ex library to my delight) from abebooks and re-read it. Oddly my memories of the book have hardly been touched by the later reading - I can still remember how I felt about it 40 years ago (identifying deeply with quite a few of the characters, not just the main girl) but hardly remember how I felt a few months ago reading it again.
