Query: Disappointing...not what I hoped for.

The scientific experiment funded by the FBI to give agents the ability to live inside the mind of a serial killer in order to understand how he thinks and what he might do next sounded good on paper. Unfortunately it may have worked too well. The project is cancelled.Former agent Arden was part of this experiment.Her parents are murdered and the killer is sentenced to be executed. Right before he dies though he confesses that while he is guilty of many other killings, he did not killer Arden's parents.Arden is given this information about the same time she finds out that the cancelled project may still be going on.It's up to her to find out who the real killer is, what effect the faulty project may have had on her while stopping an on-going killing spree.This book jumped around a lot and not in a good way. It was difficult to follow at times. Not a great read.
