Fourteen-year-old Carson Affeldt wakes in a subterranean room. He has vague recollections of a man in a forest, but everything else about his abduction is hazy. What he sees around him makes no sense.
What Carson doesn't know: Three other boys are dead, their bodies discarded along wooded trails in rural Pennsylvania and New Jersey. Whoever killed them concealed their faces behind expressionless white masks. The FBI assigns David and Martin Yerxa to investigate. As they track the path of a predator, Martin sees similarities to a serial killer he pursued during his earliest days with the FBI.
Together, father and son will struggle to understand the mind and motivations behind these unconscionable crimes as they fight to find Carson before it's too late.
