When seventeen-year-old Olivia Davies receives a phone call from her estranged father in the middle of the night, she's in for a huge shock. Her father is getting married - again - and he wants her to be at the wedding. So over summer break, Olivia packs her bags and makes the trip back to England to meet her future stepmother. But instead of the middle-aged woman she expected, Olivia finds herself introduced to Emmy Balfour, a stunning blonde young enough to be her sister. And if that wasn't enough, she also finds herself dealing with the disapproval of Emmy's older brother, Ian, a man for whom "polite" and "respect" seem to be four-letter words. With only three weeks until the wedding, Olivia struggles to stay afloat while navigating the treacherous waters of wedding planners, aristocracy, and bridesmaid's dresses - not to mention the bridesmaids in the dresses. But just when she thinks everything is finally settling down, a few well-timed lies threaten to destroy her father's chance at happiness. As a last resort, Olivia must work with Ian in an attempt to set things right, a partnership that forces her to decide if keeping him at a distance or disregarding her first impressions of him will cause her to step up and make a few changes in her own life.
