This book is pre Alex Cross and certainy not as good but it definitly comes off strong. It is not about serial killers however,and that may be a fresh change in his books. Or refreshed whichever way you look at it since it has been rereleased. That aside, I found this book to be very fast paced and exciting. While some things are predictable (unlike his current works which leave you with the feeling that you will never know what will happen) this book is still very much worth the read. Arch Carroll ( the main character) is not as deeply defined as Alex Cross but this never takes away from a great story that will move you along nicely. I am a fan of great "national security" type books and found this one very satisfying but if one is in the market for a serial escapade then this is not the book for you. If you are in the mood for an abridged Clancy type book then by all means have at it. Will not disappoint!
