1 thought on “Sigma Force”

  1. I’ve been a fan of thrillers since I read my first one way back in my teens (a long time ago lol). James Rollins has taken that genre and made it his own with the Sigma Force series. The thing that I love about these is that it is a continuing education, a long form story and a great read each time out. Each book is thoroughly researched and I find myself stopping reading to google things that he mentions. He’s always right on the money and when he mentions something, you can be sure that he is teaching you something new.

    I think Rollins is one of the best thriller/adventure writers of a generation and the Sigma Force book are his crowning achievement.
