"Hanging by the Thread" by Donald Anderson

Scary to some degree, this book is about a cult who wish to overthrow the government. This has great fiscal implications--or at least, the author likes to focus on the economics. Like any story with a group of villains, someone is in the way. The "good guy" knows what is going on, and the back-and-forth begins. There are a lot of fast scenes. Most chapters include times and locations to give the book a spy feel. The economics are explained, but appendices in the back clear up any confusion. The actual book has the American flag a bit faded on the cover.
