       Sigma Force is a division in DARPA.
       The Defense Advanced Research Projects Agency is a real agency of the United States Department of Defense “established in 1958 to prevent strategic surprise from negatively impacting U.S. national security and create strategic surprise for U.S. adversaries by maintaining the technological superiority of the U.S. military”, according to its official website. This means that it seeks out any scientific development to see how it might be used to help the country or, if it is dangerous, how it might be countered.
       The SIGMA Force division is referred to by the author as "killer scientists". Each member of the Force is a highly trained operative who also happens to be a skilled scientist, specializing in various disciplines to have the expertise to handle whatever comes up.
       The rationale behind the Force is the ever-expanding scientific breakthroughs, many of which could have devastating effects on the world is they fell into malevolent hands. It is the task of the members to try to keep that from happening and, when it invariably does, to find a way to resolve matters.
       As the series starts, the lead agent for the group is Painter Crowe and he is the star of the first book. At its conclusion, he is promoted to running the division and from that point, his colleague, Grayson Pierce, is the primary agent in the field. Crowe is definitely management material as he has a keen analytical mind that sees beyond the obvious facts and puts the pieces together quickly. Pierce, no slouch in the brain department, is more of a man of action and seems to have more an emotional attachment to his work, or perhaps because he is the star for more adventures, it just seems that way.

1 Sigma Guide Sigma Guide
Written by James Rollins, Greg Cox
Copyright: 2012

According to the author, this is "a comprehensive and detailed journal that is full of details, factoids, summaries, and NEW information about the Sigma universe."


       I have been a techno-junkie since it first started back in the early 80's. Most of those adventurers mixed military hardware with cloak-and-dagger activity. Mr. Rollins has given the readers a new form of techno-thriller, replacing planes and subs with science.
       Throw in a good dash of the mystic (I hesitate to use the world occult as that gives off an incorrect connotation) and you have a series with a lot of excitement with enough realism that you end up thinking, "I hope he just made that up!".
       I expect to be enjoying Mr. Rollins' SIGMA Force adventures for some time.

I liked Rollins from the first, and certainly after the Alistair Maclean like Ice Hunt, but with Sandstorm the prequel to the Sigma Force series he took me over the edge. These are high octane intelligent and playful thrillers with outlandish plots often based on damn good science. It is always a pleasure to see what Rollins will come up with next. He is likely my favorite of todays thriller writers.
