The Surrogates by Robert Venditti

In a near-future society where people live through flawless, remote-controlled robotic avatars that allow them to feel and act without exposing their physical selves, a law-enforcement officer is pulled into a violent mystery when a series of surrogate deaths coincide with the unexplained deaths of their human operators. As the investigation digs into the companies and cultural forces that made surrogate life ubiquitous, the officer confronts conspiracies, questions of personal responsibility and identity, and the corrosive effects of outsourcing intimacy and risk to machines.
