At the Billionaire's Bidding (The Wedding Auction)

the long version

Spending day and night in a luxurious mansion might be fun for others, but Caroline O'Donald thought it sheer torture! Because Gideon Tremayne, her sophisticated, sensual, sinfully wealthy employer, was far too tempting for a poor working girl. And he was beginning to suspect it. . . Goes the Bride! When he'd 'bought' charming Caroline's hostessing services for the summer, Gideon had wanted someone to throw off his matchmaking relatives. Someone to help turn his imposing mansion into a cozy home for one. Someone who wouldn't threaten his bachelorhood. Well two out of three wasn't bad. . . The highest bidder wins love!
