I saw Jonathan Coe recommending this on his twitter feed (he's written the preface to the more recent editions, although that wasn't on the audiobook I had).
Story in between the wars - Judith is a girl living in the country next to a house which is holiday(?) home to four cousins who seem to trail glamour wherever they go. The book follows Judith's interactions with the cousins, and what happens as they all grow older.
I can't remember much about this now except that she used the word "daresay" quite a lot and I fell in love with it, and that I loved the book. I'm going to have to read it again.
