I read Body Count, the first in this series a couple months ago and really looked forward to number two. And I wasn't disappointed.
A couple of dead bodies turn up with similar signatures to prior crimes, but not quite. Profiler, Sophie Anderson, is on vacation but can't stay away from the case. Her visions won't let her. And it looks like the victims are being lured into a fake reality show situation by a quartet of serial killers who have formed a twisted online club.
What I liked was that the investigators had to really work hard to find the clues that led them to figure out what was happening - they didn't figure it out too soon. A complex killer system like this would take a lot of outside the box thinking and investigating and that was delivered. I liked how the pieces fell together and though I "knew" the twist at the end, it was satisfying.
