This time Kat finds herself as a Robin Hood of sorts. Stealing precious artifacts and returning them to their rightful owners. She is contacted by an older woman named Constance Miller, who requests the assistance of Kat and hew crew in retrieving a supposedly cursed Emerald that several thieves have tried and failed to steal. All the characters are back this time around. Though this time they have a smaller, but just as valuable role in the book. 
 If you are looking for a fun and light contemporary read then I would recommend Uncommon Criminals. It isn't completely necessary to read Heist Society first, but you would definitely understand Uncommon Criminals more if you did. This story had a couple of surprises and twists that made the story more enjoyable. It was easy to get sucked into Kat's world and I loved every second of it.
