An Ali Reynolds book and as any book by J. A. Jance it is a keen thriller dealing physiology effects of cyber bullying. High Noon Enterprises staff is involved, especially Stuart Ramey. An old friend, Roger McGrath is missing from his cruise ship and is presumed dead. His Aunt asked Stuart to find out what happened. Ali and B decided that High Noon will take the case. Cami is sent on the same cruise to interview anyone who had met Roger McGeary. Leland gives Ali noticed that he plan to return to England. Meanwhile, we are introduced to Odin and Frigg. Ordin is the name a cyber self-taught expert, Owen Hansen. Owen created Frigg, an artificial intelligence machine. Odin selected his victims from an unstable person who had suicide in their family. He sends cyber posts to their iPhones and watches the victim’s reactions on their phones. The ending is unusual and while not a surprised to me, very satisfactory. I recommend this book. Disclosure: I received a free copy from Touchstone through NetGalley for an honest review. I would like to thank them for this opportunity to read and review the book. The opinions expressed are my own.
