3.5 actually. I didn't like this one as much as the last two. I feel like it was more of a set up for the next book more than anything else. This book was still loads better than the first one. The ending of this was really great. Cammie's grown up a lot throughout the series, and I"m glad she's moving towards getting the answers she needs. I still love Zach. He's trained to be an assassin, but he still just wants to protect Cammie. I'm surprised at how much I"m enjoying this series.
