Edith Wharton 
Twilight Sleep 

The celebrated author of The Age of Innocence offers a biting satire of Jazz Age society in this tale of indulgence, infidelity, and family dysfunction. Nona Manford is in love with the wrong man—or at least, she’s in love with a man whose wife won’t grant a divorce. When she isn’t preoccupied with her own romantic dilemma, Nona is busy trying to save the marriage of her stepbrother, Jim. But Jim’s wife, Lita, is desperate to escape her domestic role for a life of dancing, champagne, and glamour. And meanwhile, the family’s older generation isn’t faring much better. An instant bestseller when it was first published in 1927, Edith Wharton’s Twilight Sleep is both a scathing satire of Jazz Age frivolity and a psychologically probing portrait of a family coming apart at the seams.
