A complex thriller with a hacker-centric plot and polished technological descriptions.

-Kirkus Review

…I was fascinated with the authors’ attention to detail while completely enthralled with reading The Enigma Factor,… I cannot say enough about this book. If you like stories that encompass history, adventure, with all the complexities of betrayal and intrigue faced by those who provide security for the financial sector, then you will enjoy this work.
