'You are reading this because I am dead.' Something terrible happened at the Rewar Teng Institute of Experimental Methods. When the Tensorate's investigators arrived, they found a sea of blood and bones as far as the eye could see. One of the institute's experiments got loose, and its rage left no survivors. The investigators returned to the capital with few clues and two prisoners: the terrorist leader Sanao Akeha and a companion known only as Rider. Investigator Chuwan faces a puzzle. What really happened at the institute? What drew the Machinists there? What are her superiors trying to cover up? And why does she feel as if her strange dreams are forcing her down a narrowing path she cannot escape?
