Overall Content Rating: Restricted R
This is an adult thriller about federal agents and allies pursuing a dangerous criminal nicknamed the Toymaker. Dialogue among professionals and family members under stress includes frequent harsh language, from mild expletives to very strong swearing, often during investigations, internal conflicts, and life-or-death confrontations. Violence is a major part of the reading experience: characters face ambushes, torture-like threats, and multiple on-page killings with bloody, sometimes graphic detail. Parents should also know that sexual assault appears in the story as part of reported criminal behavior rather than as romance; it is described in summary fashion during an investigation. Horror-style tension, menacing set pieces, and distress involving teens and colleagues in peril run throughout.

About this book
Hope is lost. On a small island off the coast of North Carolina the unthinkable has happened; 400 people have vanished without a trace. So far every government investigation has been stymied in their attempts to explain the sudden mass disappearance. Now as the public clamor for answers the very people tasked with finding them start to disappear as well, leaving many to wonder if what caused the vanishing is still lurking on the island? Consumed by darkness. Caleb Fine is a changed man. The events of Toronto have left him wracked by guilt and filled with a barely constrained rage. The search for the Toymaker is no longer about justice for him—the killer has made it deeply personal. Now nothing and no one—including the FBI—will stand in his way. In the realm of shadows… Following a trail of obscure riddles and scant clues, Caleb finally discovers where the Toymaker has gone to ground. With the aid of his partner, Li Ling Tran, he heads into the unknown to find that in the shadows of his soul, a promise softly spoken has become tragically true. Nothing will ever be the same again.
