Cat has a dangerously dwindling bank balance. She also has:
* a month before her landlord kicks her out
* a surprise wedding invitation from rich mean girl, Louisa
* a secret talent for con artistry
A priceless jewel the size of a cocktail olive is glinting on Louisa's finger.
And when Cat meets her ideal plus one, Jake - who's gifted at hustling and posing as the perfect boyfriend - this wedding becomes a once-in-a-lifetime opportunity. After all, how hard can a diamond heist be?
