Ok so lets start with James Rollins. Any fans of the Sigma Force series?
Sandstorm
Map of Bones
Black Order
The Judas Strain
The Last Oracle
The Doomsday Key
The Devil Colony

I enjoyed all of them. Have not read the ones released this year 2013, Bloodline or The Eye of God. Not sure if the same Sigma Force characters are in the newer two. Anyone read them yet?

Not familiar with those. What's the basic story line?

In a nut shell, Sigma Force is an elite covert arm of the US Defense Department made up of former Special Forces officers trained as experts in various scientific fields.
I enjoyed the series as the characters remained consistent and the story lines really grew from book to book without getting predictable.

To answer my own question, ALL of the characters re-appear in the 2013 book, Eye of God. Just finished it and it was as good as all the rest of this series. Have two of his other books going to start now, not related to the Sigma novels.

Sandstorm (2004)
Map of Bones (2005)
Black Order (2006)
The Judas Strain (2007)
The Last Oracle (2008)
The Doomsday Key (2009)
The Devil Colony (2011)
Tracker (2012)
Bloodline (2012)
The Eye of God (2013)
Sixth Extinction (2014)
The Bone Labyrinth (2015)

Up to date list for those interested.
