Goslings [EPUB ebook] 

When a worldwide plague kills off most of England’s male population, the highly conventional Mr. Gosling and his daughters begin to fulfil "long-thwarted tendencies and desires." Gosling abandons his family for a life of lechery, leaving his daughters-who have never been permitted to learn self-reliance-to loot abandoned shops. Eventually, the Gosling girls find a place in a female-dominated agricultural commune… but their new life is threatened by their elders’ prejudices about free love! (Goodreads)
