I did enjoy reading this book, but it fell a little short of the first one. Katie's parents come to New York for a visit and at the same time another crisis has hit MSI in the form of a spy. This led to some humorous moments. What bothered me is that Katie missed a couple obvious-to-me clues and as a result made things worse for herself. I have trouble believing that the Katie from the first book would have taken so long to figure a couple of things out. Otherwise it was a really fun read. I'm definitely going to move on to the third book in this series.
