The Sixth Extinction by James Rollins (audio book )

This is part of The Sigma series. It needs to be read in order, the first book is Sandstorm.

     This is book ten in the series. Not disappointed, though this book seemed to be shorter than I expected. 15 discs, int the audio book.
     This is a typical James Rollins book. The right balance of action, science, history, and characters you love to keep following and routing for.
     This tale does have a few big changes for characters in it. Never too much action or to little. A roller coaster ride of a tale, a perfectly woven tapestry of a tale. One that soon hooks who and never lets go till the end, leaving you waiting for the next mission.
