Good entry to the Sigma Force series. Lots of twists and turns, high octane chases.

Snippet of historical fact, create backstory......check. Jump to today where something from said backstory is being used to threaten humanity......check. Event occurs that alerts SIGMA to said threat......check. SIGMA begins globe trotting to discover key (like how I did that?) to stopping said threat......check. Some sexual tension between characters......check. SIGMA overcomes all obstacles, figures out key to stopping said threat and saves the day......check.

This is the formula to a James Rollins SIGMA novel and is why I will pick up and start reading without even checking the storyline. As usual a fun and entertaining read.

This was a decent book to listen to. It helped to pass the time while driving on vacation.

I always love the mixture of fact and fiction in James Rollins books and this one is no different!

Best Rollins yet (haven't read his latest one). Great story, and the characters finally have begun to really develop and set up for future novels in the Sigma Force series. I especially like the love/hate relationship between Pierce and Seichan, mortal enemies but seem to need each other in weird, twisted, adventure novel sort of ways.
