The Gatecrasher by Madeleine Wickham
Everything's coming up roses for Fleur Daxeny, as she goes through more rich men than she does designer hats. Beautiful and utterly irresistible, her success at crashing funerals to find wealthy men is remarkable. Fleur wastes no time in seducing her latest conquest, the handsome and rich widower Richard Favour. His children are caught up in a whirlwind as their father's new girlfriend descends on the family estate. Fleur is not one to wear her heart on her Chanel sleeves, but she soon finds herself embracing Richard and his family. But just as Fleur contemplates jumping off the gold-digger train for good, a long-buried secret from her past threatens to destroy her new family.
Take a wild and marvelous ride with The Gatecrasher, whose clever, chic, and sassy style will leave you desperately wanting more wonderful Wickham!
