This is a startlingly good book. It is a long time since I read something where both the characters' internal life and their external realities were so fully and convincingly evoked. It looks, among other things, at England during the first world war from an aspect that I had never seen explored before. It makes me think of Dickens, in the best way, compelling and intriguing characters, without any grotesqueries, complex, flawed and humanely, by which I think I mean sympathetically treated.
