The 6th Extinction

Standard Rollins Sigma thriller, which is a compliment. Usual potpourri of science, adventure, exotic locales.

I liked it...It satisfied me...and That's enough for 4 stars....

This was one of our car trip listens. Lots of interesting science...author explains fantasy vs. reality at the end.

The bad guys plans were really scary in this one and the bad guy himself was less cartoony than in other books.
The parts that happened in Antarctica where exciting and interesting
