As a professional bridesmaid, Sophie Breeze is hired by London brides to be their right-hand woman, posing as a friend but working behind the scenes to help plan the perfect wedding and ensure their big day goes off without a hitch. When she’s hired by Lady Victoria Swann for the society wedding of the year, it should be a chance for Sophie to prove just how talented she is. Of course, it’s not ideal that the bride, Lady Victoria’s daughter, Cordelia, is an absolute diva and determined to make Sophie’s life a nightmare. It’s also a bit inconvenient that Sophie finds herself drawn to Cordelia’s posh older brother, who is absolutely off limits. But when a rival society wedding is announced for the very same day, things start to get…well, complicated.
