Polly Atkins is getting married. And her older sister Bella couldn't be more excited. Not only will Polly be home after five years in New York, but she's coming back to marry the most perfect man on the planet, Dev. Dresses, cake, first dance ...Bella's looking forward to getting stuck into the arrangements. Polly's best friend Grace is just as excited. She's can't wait to walk down the aisle behind her childhood ally, especially as the stylish Polly wouldn't dream of dressing her bridesmaids in anything but the best, which will make a welcome change to the 'mum-wear' she's adopted since her second child was born. The only person who doesn't seem to be bursting with enthusiasm is Polly. Which is why, before things can get any more chaotic, she calls the whole thing off.

But she's reckoned without Grace and Bella, who are determined to get Polly and Dev back together if it's the last thing they do. After all, solving someone else's problems has got to be better than dealing with their own ...?
