The Passionate Prude

A scandalous entanglement traps a woman of virtue in an unforgettable Regency romance from the bestselling author praised as "a major find" (Mary Balogh).
  
When word reaches Deirdre Fenton that her brother is pursuing the notorious actress Mrs. Dewinters, she immediately sets about extricating her incorrigible sibling from his latest folly. But her brother has gone too far this time for his—or Deirdre's—own good. For Mrs. Dewinters is under the powerful protection of a war hero, the Earl of Rathbourne...the very man Deirdre had summarily rejected years before. And the Earl is not a man to forgive an insult—or forget a lady as passionate as Deirdre Fenton...
 
If Rathbourne has learned one thing during his years fighting on the Peninsula, it is to get what he wants by means fair or foul. Now he has Deirdre right where he wants her: at his mercy.
