Fourth Day by Zoe Sharp is the eighth book in the “Charlie Fox” thriller series. Publisher: Pegasus, February 2011

The cult calling itself Fourth Day is well funded and highly jealous of its privacy. Five years ago Thomas Witney went in to try to get the evidence that the cult’s charismatic leader, Randall Bane, was responsible for the death of Witney’s son, Liam. Witney never came out. Now, Charlie Fox, and her partner, Sean Meyer, have been tasked to get Witney out, willing or not. But planning and executing a clean, surgical snatch is only the beginning. Five years is a long time to be on the inside and the man who comes out has changed beyond all recognition.

Can Witney be trusted when he says he now believes Bane is innocent of the crime and, if he is, who was behind the boy’s demise? Searching for answers, Charlie agrees to go undercover into Fourth Day’s California stronghold. A fast covert-op. No real danger for someone with her mind set and training. But Charlie has her own secrets, even from Sean, and she’s not prepared for the lure of Randall Bane, or how easily he will pinpoint her weaknesses.

What a great ride. This book pulled me in immediately as Charlie and Sean take on their next case that involves a rescue attempt from a cult organization. Things don’t go as plan and Charlie goes undercover with some surprising results. This suspenseful thriller kept me on my toes as I watch Charlie do what she does best and try to take control of her internal demons. With an explosive conclusion, I can’t wait to read the next book in this intense and gripping series.
