I'll be honest, I remember not liking this story that much when I originally read it. Now that I have re-read this story, I do not know why I disliked it before, but I still don't find this story all that interesting. There is a lot of actual Washington D.C. places and buildings listed in this story and I have a better appreciation for that information now, but that doesn't change my overall feel for this story.
With all that said, I do feel like this story needs some follow up books to help us find out what has happened to Nadine and maybe even Maddy over the years.
