Someone to Watch over Me — Tricia Sullivan

MIND CONTROL

In a future where hidden Watchers can inhabit the bodies of well-paid slaves via satellite link, identity is no simple matter. For Adrien Reyes, life as a surrogate body is a trap he's desperate to escape. For Sabina Lazarich, it seems like a chance at true empathy. What neither of them realizes is that the experimental brain implant I--currently the hottest technology on the black market--could afford a reclusive, dying Watcher known only as C a second chance at life.

Because C intends to download itself permanently--into one of them.

And C is a dangerous animal. It has made an enemy of the Deep, a vast and mysterious network of minds that will do anything to get control of I. For the implications of this technology could signify the end of the "self"--and metamorphosis for humanity.
