Emma Oxley and Nellie Yarrow have been inseparable their whole lives. Ever since they reinvented themselves, changing their names and wiping clean their digital footprints, they have made a game of following wherever the next adventure leads and challenging themselves to thefts, street cons, and mind games.

Adhering to only two rules--they will only swindle men, and only ones who deserve it--Emma and Nellie are secure in their reputation as the most trustworthy swindlers on the European black market. Until suddenly, they must play to save their own lives.

Blackmailed into stealing a priceless bracelet from a high-security exhibit, Emma will reexamine everything she believed to be true. This heist takes her far beyond her comfort zone...and she and Nellie will need allies among the glitzy bejeweled gathering in London in order to survive. Will they be able to do the right thing before it's too late?
