Virtual sabotage
(Book)

Virtual Sabotage introduces Kenna Ward, an envoy for a virtual reality company whose implants create a thrilling world that allows people to create daring scenarios in a safe environment. Most of the time, that is. When in the rare instance the human brain mistakes the terrifying event as real, it's up to Ward to enter the scenario and pull them back to reality. But when a key envoy goes rogue and people begin responding in odd and dangerous ways, Ward delves deeper, finding a sinister conspiracy to take over not only the virtual reality world, but the real one as well.
