The Lark: Edith Nesbit

"When did two girls of our age have such a chance as we've got - to have a lark entirely on our own? No chaperone, no rules, no..."
"No present income or future prospects," said Lucilla.

It's 1919 and Jane and her cousin Lucilla leave school to find that their guardian has gambled away their money, leaving them with only a small cottage in the English countryside. In an attempt to earn their living, the orphaned cousins embark on a series of misadventures - cutting flowers from their front garden and selling them to passers-by, inviting paying guests who disappear without paying - all the while endeavouring to stave off the attentions of male admirers, in a bid to secure their independence.
