Judgment Zero (An Agent Zero Spy ThrillerBook #23)
"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
