The Buccaneers by Edith Wharton and Marion Mainwaring (Trade Paperback)

Set in the 1870s, the same period as Wharton's The Age of Innocence, The Buccaneers is about five wealthy American girls denied entry into New York Society because their parents' money is too new. At the suggestion of their clever governess, the girls sail to London, where they marry lords, earls, and dukes who find their beauty charming—and their wealth extremely useful. Marion Mainwaring has finished the story, taking her cue from Wharton's own synopsis.
