Hey, Char, have you read this one? I know you are such an Edith Wharton fan!
Undine Spragg is our main protagonist. She is new money, Midwestern, heir to a druggist fortune, named after a hair straightening solution released the week she was born. Father is firmly nouveau riche, Undine has aspirations above her station. This is the third in a cycle of New York stories written by Wharton which I have read, in addition to The House of Mirth and Age of Innocence.
Wharton is up there with Austen, Gaskell and Cather for me.
