Hudson Hopper is in some trouble. After doing his business partner a favour by hiring his younger sister, Sloane, as his assistant, Hudson very quickly finds out that she is a massive distraction.

But when Sloane is asked to fill in as a bridesmaid for another of Hudson's business partners, she comes up with an equal trade. She'll be a part of the regency-themed wedding - corset and all - if Hudson marries her. Sloane knows the value of the trade: he needs her, and she needs his wedding ring to get her into a high-society club and further her career.

It's an instant no from Hudson at first, but when she convinces him that no one will find out - including her brother - and that he will certainly benefit from the marriage too . . . well, Hudson suddenly finds himself saying 'I do.'
