The Enigma Strain

The plot was fast paced, compelling, and fun to read. The charterers weren't as strong and at times there was too much telling us who they were instead of showing us who they were. Overall, good read, but not his best work.
UPDATE:
This series gets better as it goes along. There is a lot of world building in this one and I didn't love it. But it was important ground work for the other books and it was a fun race to save Yellowstone.
