This is book 3 in the series, but chronologically it is actually book 1. This is a stand-alone book and does not need to be read in order.
When someone you love vanishes, how far would you go to get them back?
Young girls are disappearing in groups of three, their bodies callously discarded by a killer whose methods stun even the most seasoned detectives. Agent Skeeter Perkins is a world-renowned profiler. He’s been with the FBI for over a decade and has made a name for himself catching the worst serial killers known to man. His current case, a man the media has dubbed the “Scientist” is no different. But, when Perkins and his team start to close in, the stakes become personal. Skeet must put everything on the line as he plunges headlong into the most desperate hunt of his life.
