The Doomsday Key by James Rollins is the sixth book in the Sigma Force series, but reading the previous books is not required to understand or enjoy the book. This was my first book by Rollins and I enjoyed it so much I read the last half in a single evening. As a matter of fact, I now plan on reading the rest of the series.

Sigma Force is a special black ops group that has a very wide range of skills and duties, similar to ‘Mission: Impossible’. This time around, two separate and seemingly unrelated incidents peak Sigma’s interest for different reasons; the group soon discovers that they are very much related and are only the tip of the iceberg. Someone has found an ancient biological weapon and has plans for it’s dissemination –  all they need to do is find an antidote to protect those chosen. Sigma Force gets tangled up in the plot while trying to figure out who’s doing what and why.

The Doomsday Key was an exciting fast-paced ride that started on page 10 and didn’t stop to let anyone off. As a matter of fact, it kept picking up speed until the end. Helping keep the pace, the chapters were relatively short and each was broken down into sections with time stamps as we jumped back and forth between different groups doing things concurrently. I thought the book was well put together and really enjoyed the story. It captured my attention and didn’t let it go. I highly recommend it for those who enjoy spy thrillers of the action kind.
