You are cordially invited as two con artists fake-date their way into the poshest wedding in town.

Single, broke, and about to be ejected from her London flat, Cat feels left behind by her friends, who are all either married or engaged. At least if she picked a few pockets when fellow wedding guests get handsy, no one's the wiser. No one, that is, except her favorite bartender, Jake, who has his own less-than-legal side hustle.

When she's unceremoniously fired and roped into bridesmaid duties for best frenemy Louisa, Cat can't help but notice that Louisa's priceless diamond engagement ring sure would solve a lot of problems. But Cat isn't as skilled a thief as Jake is, so to pull off the scheme of their lives, they'll have to pair up. From an engagement party on a boat to the bachelorette weekend in Palermo, Cat and Jake play cat and mouse with each other in a romantic charade. But who's to say what's real and what's fake, when love and money are on the line?
