One DNA sample. Three suspects. The perfect offline flight thriller. Read the novel anywhere. # One DNA sample matches three people – all alive, all with alibis, all unknown to each other. Dr. Saya Torres expected routine forensic work: evidence analysis, DNA matching, standard procedure. Instead, the DNA links three living suspects to one victim. The case exposes an underground network manufacturing untraceable humans. ZERO SUBSTRATE is an interactive forensic thriller built natively for iOS. Detective fiction meets investigative narrative wrapped in a terminal-style interface. TRY CHAPTER 1 FOR FREE Experience the introduction of the investigation completely free.
