I dearly love all of L.M. Montgomery's writings! I have the whole collection and there's many of her short stories that are up there with all time favorites. (and some that she's recycled to/from other stories)

I've reread all of her stuff about yearly and well, it was very formative. :)

My favorites (so hard) are: Rilla of Ingleside, Anne's House of Dreams (I love the Leslie story), The Blue Castle, Kilminey of the Orchard, and... um... I'll stop there. (I'm a hopeless romantic ;) )
