Evelyn Sharp 
Youngest Girl in the School [EPUB ebook] 

Victorian children’s literature featuring a spunky young heroine. Babs was supposedly sent to Coventry for weeks by her classmates, but she spends so much time engaging in maladaptive daydreams that she never even notices, and when she does she’s grateful they leave her alone so she can daydream some more. Even when her classmates forgive her, they are used to her talking to herself and making no sense, because she’s always away with the fairies. But everyone adores her. (Goodreads)
