The Perfect Kiss — Anne Gracie

To rescue her friend...
Grace Merridew's childhood has made it hard for her to trust men and in three years on the marriage market, her senses have never been stirred. So she makes plans for a life of adventure instead--to see the moon rise over the pyramids of Egypt and dance amid the marble ruins of Greece. But first she has to help a friend.

...she must enter the lair of the Wolfe.
Grace's timid friend is being forced to marry Dominic Wolfe, who stands to inherit a huge estate if he weds. The Wolfes have a terrible reputation, and if there's one thing Grace cannot stand, it's a bully. Her friend begs for help to escape this marriage, so Grace acts as the plain and mousy chaperone on their visit to the groom-to-be. But when they arrive, nothing is as they expect, and Grace is scandalized to find herself being pursued by a big bad Wolfe with dishonorable intentions.
