“You will not sleep until you are finished with AGENT ZERO. A superb job creating a set of characters who are fully developed and very much enjoyable. The description of the action scenes transport us into a reality that is almost like sitting in a movie theater with surround sound and 3D (it would make an incredible Hollywood movie). I can hardly wait for the sequel.”
--Roberto Mattos, Books and Movie Reviews

What a ridiculous book. I can’t believe there’s 17 books or more in the series! The majority of the time the three agents are just complaining and having a battle about who loves who the most! I can’t count how many times they stopped during action to claim the woman was more important to them than the other man. This was so stupid. And then at the end, when the whole facility blows up and yet the lover who was left behind for dead miraculously survives??? and then the helicopter shows up right then to rescue them in the middle of Antarctica with no call or alert to them that they were in trouble??? And not to mention that the girls fighting these highly trained terrorist assassins are 16 years old! Yet no harm comes to them? This was just terrible plot and terrible writing. Booooooo!!! Two big thumbs down!
