The only rule is the rules always changeModelling gave Lillian McDermott amazing experiences and enough money to leave it all behind to start her own perfume and fashion label, but it didn't give her the man she's always loved--Mackenzie Harris.Her brother's best friend, Mac only sees her as a surrogate little sister, except Lillian's success wasn't handed to her. She knows what it means to work hard and she intends to use the same single-minded intensity to rock Mac's world until ignoring her is impossible.Best mates don't screw around with little sisters so no matter how tempting Mackenzie Harris finds Lillian McDermott it's hands off. That doesn't mean he's ever been immune to her charms.With one spin of the bottle Lilli turns up the heat and Mac's not one to back down from a challenge. And once that line is crossed, there's no turning back.Note: A game of Spin the Bottle is hell on one's self control.
