The Devilish Duke (Unabridged‪)‬

Miss Rosalind Weaver is on a mission. She must convince the Duke of Fallon to marry her, or her father will give her away to the next highest bidder, a man she cannot stand. She thinks all the Duke desires is reassurance that she can give him an heir. But she soon learns he wants a more thorough test of how she will fare as his wife - in the bedroom.
