Ally Carter is one of my favorite authors. I love her books with an insane love, and that creates high expectations. While Ally's Gallagher Girls series just gets better and better with each book, for me, the Heist Society series starts out strong and then tapers off a little with each book. I LOVE Kat and Hale's relationship, but I had the teensiest bit of a hard time with this book. It was good--everything Ally writes is good--but it wasn't my favorite. I hate saying that about a series and an author that I love, but for me, Heist Society is the best book in this series. 
 Now don't get me started on how much I fanatically love the last three books of the Gallagher Girls series...
