There are two major flaws with Miss Carter’s storytelling in this novel. First, she relies too heavily on “The Henley” from the first caper. Yes, it is an impressive and essential element of Kat’s back story, but the frequency of reference to that particular heist makes it into a crutch that is both repetitive and annoying. Can't this book stand on its own?
The second major flaw is characterization. Despite the fact that Ally Carter has written two full books about these characters, she doesn't seem to know them very well. Relationships between protagonists are flat, and interactions are insincere.
Despite all of this, the book may have reached the four-star mark if the moral of the story didn't bludgeon you over the head at the very end.
Overall, Uncommon Criminals gets just three stars, despite the author’s best intentions.
