The 4th Anne book has two different titles depending on whether you get the British or the American version (apparently the American publisher feared people would confuse "Windy Willows" with "Wind in the Willows"). LMM herself wanted to call it AoWW, so that's what I consider the 'proper' title myself. Also, I've been told that AoWP is abridged compared to AoWW, but I haven't checked myself.Many people find AoWW the weakest of the Anne books, because we hear so little about the characters of the other books. I'm not among them though. I love reading books made up of letters, so this is one of my favourites. The last star was removed solely because there were some of the plotlines/characters I didn't care about at all (e.g. Gerald and Geraldine... or whatever their names were ;) ).
