The Frog Earl (a Regency Romance‪)‬

Escaping into the countryside to nurse his wounded pride and heart, Simon Hurst encounters the lovely but eccentric Mimi (half English, half Indian and all mischief) who promises him three favors--then only grudgingly doles them out. If he can capture that last one--that kiss--before she learns the truth about his identity, he should transform into an earl once again.  Regency Romance by Carola Dunn; originally published by Walker.
