Book 2 in the Kristian Clark and the American Agenda sub-series.
"And Eden were no Eden thus exposed… He found himself only to be stolen again. This time, though, it is not Kristian’s mind that is lost, but his soul. Suddenly without a conscience, the man formerly known as Kristian Clark has only goal: to make sure that no other being controls him again despite his weakened state. Whatever that means, and whatever it takes."
