It is a warm and lovely mid-summer morning and Special Agents Nicolas Drummond and Michaela (Mike) Caine, are just settling into their idyllic rest vacation at Nick's grandfather's, the eighth Baron de Vesci, home estate in Farrow-on-Gray in England. Finally starting to relax and heal after their last adventure, a call from the FBI in Washington, brings very unsettling and disturbing news.

Before they can begin to appreciate that the vice chancellor of Germany has been assassinated, more disquieting news comes and Nick soon finds out that his grandfather's company, as well as, the supposedly secure British security system have been compromised. Despite being on vacation, Nick feels confident that he can help resolve the ransomware attack. Both he and Mike are members of the FBI Special Covert Eyes unit and they have considerable contacts, as well as, special training and talents. Yet, will those resources be enough for this new and unknown enemy? Who is funding these attacks? What is behind these shocking attacks on political and extremely wealthy business leaders? Will London be destroyed? How can they stop this highly successful and smart enemy from winning?

THE SIXTH DAY is the fifth book in New York times bestselling author Catherine Coulter's highly regarded A Brit in the FBI series. While THE SIXTH DAY is a highly suspenseful and captivating read on its own, existing fans of Coulter's books are sure to relish the return of Nick, Mike, and other key characters in this latest addition. There is definitely great chemistry between the characters and they quickly and vividly come to life in the mind's eye.

Reading THE SIXTH DAY, one can easily imagine the story as a fast-paced and intense action movie. Several subplots are woven into the plot development, yet, the connections between them soon become clear. The main plot involves the scary threat of cyberterrorism with drone and falcon attacks and a linkage to a strange medieval manuscript, "The Voynich Papers," written in a strange language, missing pages, and a connection to Vlad Dracula III.

Coulter's talents as a storyteller soon pulls them together in a riveting page turning story that one finds very hard to put down until finally reaching the explosive conclusion. THE SIXTH DAY is a clever combination of European history, suspense, and modern intrigue. While I found some scenes in THE SIXTH DAY a little over the top for me, I am sure fans who like this genre will definitely get an explosive charge from this latest suspense and cyber technology thriller by the highly regarded and well known Catherine Coulter!
