The big day is fast approaching, but so is a big disaster... Sabrina Falks is the golden girl - a star actress engaged to the too-good-to-be-true Edward. Her younger sister Mimi is funny and bright but hopelessly lost, with no career prospects, no money, no love life and a string of disastrous mistakes in her past. When Sabrina asks Mimi to be her bridesmaid, Mimi soon learns that 'bridesmaid' actually means 'unofficial wedding planner - servant, slave and general dogsboddy'. And, to her horror, she knows that it's going to take more than just patience to whip up the wedding of the century, especially when the official wedding planner has a murky secret that could rock Sabrina and Edward's world...
