Refining Felicity (The School for Manners Series Book 1) by M.C. Beaton:
http://www.amazon.com/Refining-Felic...owViewpoints=1
The Misses Tribble, Amy and Effie, spinsters of a certain age, have lived for years on expectations of a great inheritance. When this fails to materialize, they are truly destitute. Desperate, they advertise that they will refine wild and unruly daughters, present them, and see them safely wed. This first volume concerns Lady Felicity Vane and the Marquess of Ravenswood in a love-hate courtship. The Tribbles are charmers and much more fun than their charges.
