Why have you read 'The Great Gatsby' but not Ursula Parrott’s 'Ex-Wife'?

In 1925, F. Scott Fitzgerald published “The Great Gatsby.” Four years later, Ursula Parrott published her first novel, “Ex-Wife.”

I probably read “The Great Gatsby” a dozen times between junior high school and my late 20s. But I had never even heard of Ursula Parrott or her 1929 bestseller until I stumbled across a screenplay adaption of one of Parrott’s short stories.
