Desperate duchesses - Eloisa James

Spring 1783 ... Jemma, Duchess of Beaumont, has just returned from Paris and is planning to shock all of London high society - not to mention horrify her husband - with scandalous soirees and a debauched Grand Ball. When her country cousin Lady Roberta St Giles asks for help seducing the Duke of Villiers into marriage, Jemma transforms Roberta into the most delicious and desirable woman in town. Then she lures Villiers to the house, ostensibly to play chess, but he, ignoring both Roberta and Jemma's husband, offers Jemma a match - the third game to be played blindfold. And in bed.
