His Fair Lady
Kimberly Lang

Miss Behavior, etiquette expert Gwen Sawyer, has only three weeks to work her magic on Evie before her debut at a major fundraising gala, so she moves into Will's luxurious penthouse ready to turn Evie into a lady. While her contract is very clear about her duties, lines get blurred when Will's interest turns from polite to passionate.
Gwen knows the rules, knows what's at stake, but sometimes it's just so tempting to...misbehave.
