I really enjoyed this book. I felt like I was reading a teen version of Ocean's 11. (which is one of my favorite movies) This book was really cute and very fast paced. There were no slow parts or parts where I was bored. 
 I liked all the characters too. Kat was very likable. She was strong and smart and she managed to pull off being a thief while still being a good person. I just wanted to push her into Hale's arms the entire book. I kept reading and thinking, "on the next page something is going to happen between Hale and Kat" and then most of time nothing happened. 
 So I am hoping in the next book more happens between the two of them. 
 I am also a big sucker for art and museums, so I loved hearing all the descriptions of the paintings and the Henley. All of the heist planning was really interesting for me too. It got me thinking and had me trying to piece together their plot. That kept me really engaged in the storyline. A few times, however; a lot was going on at once and I found myself having to re-read a paragraph to keep from getting confused. But that's only because there were a lot of high action scenes in this book. 
 Great book! I look forward to seeing what will happen next, and I can only hope to see more Hale/Kat interaction.
