A killer cyborg on the loose. A daughter’s life on the line. And one man’s secret will decide all of their fates… Designed for urban combat, the S1-R3N prototype is the ideal cybernetic soldier. But when it malfunctions during its public debut, it kills its handlers and the buyers in attendance for its unveiling. Now Dr. Grant Andrews, the scientist responsible for creating the S1-R3N, is the only one who can stop it. But the S1-R3N is determined to get to Grant first, by any means necessary—including going after Grant’s teenage daughter, Alexis. Will Grant be able to protect his daughter from the cyborg’s murderous intentions? Or will the S1-R3N send him to meet his maker?
