Kat used to be a thief (it's the family business) but she decided she wanted out and conned herself into one of the most prestigious boarding schools in the United States. But now Kat's dad is being accused of a robbery he didn't commit (mainly cause he was busy committing another one somewhere else) by a pretty scary guy. With Interpol hot on her dad's trail Kat needs to clear her dad of the second crime, or else. So Kat sets up her team and breaks into one of the most well protected museums ever.
This was an extremely fun read, think of it as Ocean's Eleven with teens and girls. Kat and her compatriots are incredibly likable characters. While technically they are criminals, they do have a code of honor that is highly important to them and their own sets of morals that are important to them. This goes a long way to making them likable. A lot of this book focuses on that code of honor and on righting previous wrongs and contextualizes an important part of how theft can sometimes be justified. (Yeah I know that sentence was really ambigious but I am trying not to be spoilery.)
