Elinor Brent-Dyer, 1934 (mine is the Girls Gone By 2007 edition).
Rather dull really. As Ruth Jolly says in her introduction, Brent-Dyer doesn’t follow through the initial themes of an isolated child, and the book becomes a very usual school story, though still with some of Brent-Dyer’s usual warmth (attitudes to younger sisters, for instance). There are a few EBDisms – when Carnation is patted on the back by everyone for saving a life, she feels like the dog in “the farmer wants a wife”.
