Those words describe MOST of the characters in this story! Savich and Sherlock are compelling people I can’t get enough of! I’ve read every book, as has my friend who told me about them several years ago.
Fast paced

This book was fast paced. There were enough stories and characters to keep one interested.

As usual the story line was so interesting and the characters so complex. This is such a a great book and a must read.

A disaster; she did not bring her “A” game to this one.

I’m a huge fan of all Catherine Coulter’s FBI series, but once again…this book was a huge disappointment. Too many characters, too many storylines. She hasn’t had a good storyline for Sherlock and Savich since The Maze.
Awesome

Grabs you from the very beginning. Savich and Sherlock each are working on different cases. Both very interesting, and both very dangerous. A great story. Highly recommended for everyone rather this is your first book featuring the two of them or not.
Coulter returns.

It is fantastic! I love all of Catherine Coulter‘s books especially the FBI series. If you haven’t read any of Catherine Coulter‘s books please do. They are all great. If you like books with characters that continue over many many books then Catherine Coulter’s FBI series is for you. If you haven’t read any yet Start with the first one The Cove.

How to mix CIA, special forces spy stuff with a murders mystery - every page a turner? Read Vortex. Simply superb.
