Authors I've Read That You Haven't Heard Of: Edna Ferber
No, seriously. Between the collections of the library system I grew up in and the prep school I attended, I must have read 20-25 of her books. Everything from Showboat to So Big. Even the book set in Alaska.
She won the 1924 Pulitzer, palled around with Dorothy Parker and the rest of the gang, and was considered the best novelist of her generation. And today she's totally Trivial Pursuit.
