The Luckiest Girl in the School is a schools fiction for girls written by Angela Brazil, the first British writers of "modern schoolgirls' stories", written from the characters' point of view and intended primarily as entertainment rather than moral instruction.

Excerpts:

"There's no doubt about it, we really must economize somehow!" sighed Mrs. Woodward helplessly, with her housekeeping book in one hand, and her bank pass-book in the other, and an array of bills spread out on the table in front of her. "Children, do you hear what I say? The war will make a great difference to our income, and we can't—simply can't—go on living in exactly the old way. The sooner we all realize it the better. I wish I knew where to begin."
