Augment Nation by Scott Overton

Since the age of fourteen Damon Leiter has had a brain-computer interface implanted beneath his skull to correct a neurological disorder. As a teenager, it branded him as an outcast—as an adult it endows him with extraordinary abilities: he may represent the next step in human evolution. When computerized brain augments replace smartphones as the must-have status item, mega-corporations and governments conspire together and marketing becomes mind control. Damon is the only one equipped to lead a global resistance movement. Caught between the fervour of his followers and the tide of rampant consumerism, he can’t be sure he isn’t playing into the hands of the rich and powerful. They may even be in the right. Maybe the real enemy of humankind is Damon Leiter.
