''...[Charlie], you're one of the most fearless. And the most courageous. You do what most of us dread, what most of us fear. I have never believed that violence was the answer to anything, but giving in to violence is not the answer either.''
Charlie Fox, ex Special Forces soldier and now a bodyguard, is back with a vengeance in this, her eighth outing, going undercover into Californian cult Fourth Day. She and her partner, Sean Meyer, have been given the task of removing Thomas Witney from within the cult, five years after he himself went in with the aim of discovering if the cult and its leader, the enigmatic Randall Bane, were responsible for the death of his son, Liam. Five years is a long time and, while Witney had left instructions to be removed if he had not come out voluntarily within a year, that deadline to try and extract him had come and gone... Why? Struggling with some personal demons of her own, the task is initially successful, but repercussions resound long after Witney is removed from Fourth Day. With more questions than answers for those on both the outside and inside of Fourth Day, Charlie faces a challenge which threatens her professionally and personally.
