The Nexus Trilogy
The Nexus Trilogy is a series of three Books written by Ramez Naam.
'In a future not so far from ours, the ingestible and illegal drug/technology called Nexus can link human minds electronically, wirelessly, nearly telepathically. There are some who want to improve it, some who want to eradicate it, and others who just want to exploit it. From San Francisco to Bangkok, from Beijing to Delhi, Nexus is a thrill-ride through a world on the brink of explosion."
