Countdown Zero

“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 COUNTDOWN ZERO is book #18 in the #1 bestselling AGENT ZERO series, from #1 bestselling and USA Today bestselling author Jack Mars (with over 10,000 five-star reviews).
