The 6th Extinction, the 10th “Sigma Force” adventure novel, is trademark James Rollins, which is to say it is everything-but-the-kitchen-sink storytelling at its most unpredictable.The doomsday thriller, out Tuesday, opens with a disaster at a military research facility in Northern California that leaves 50 square miles of toxic wasteland.To keep the threat from going global, the team of scientist-soldiers must unravel a mystery that connects the latest research with synthetic biology and indestructible viruses; an ancient map recovered from the lost Library of Alexandria; missions into Brazil and Antarctica; and a history lesson involving a young Charles Darwin and his 1832 voyage aboard the HMS Beagle.It’s no spoiler to reveal that Sigma will save the day. Rollins, who has more than 2.5 million Sigma books in print, promises at the end that the team’s “greatest and boldest adventures are still on the horizon.” Meet the author: Rollins will sign copies at 7 p.m. Friday at the Dallas Barnes & Noble, 7700 W. Northwest Highway, 214-739-1124. As chair for Authors United for Veterans, Rollins also is teaming with Barnes & Noble on a book drive.
