Six months ago, Tom Vincent was blinded in a fire. Now he has crystal-clear vision with a pair of nanobot eyes, thanks to BioMek Horizons' research and development team. His eyes seem perfect-until Tom finds that people around him are dying suddenly and violently. For the past two years, ex-mercenary Nick Wolfe hasn't had a greater purpose than getting to the bottom of his next drink. But when a letter from his old friend Tom arrives, Nick will do anything to help a friend in danger. Tom wants nothing more than to get rid of his nanobot eyes but they're impossible to destroy, and he has tried. Tom would rather live in darkness than to be used as the unwitting weapon of an evil corporation. Together, Nick and Tom must get to the truth before Tom kills again... But how do you fight an enemy who sees through your eyes?
