The Sixth Son is the second novel in a trilogy on human trafficking involving US Homeland Security Investigations (HSI) and their relentless effort to curb Mexican cartel shipments of kidnapped women and children across the US border. Unlike the prequel, The Old Cop, which involved a retired US Agent, Agustin Camelia’s intrepid efforts to battle this evil, the Sixth Son introduces a highly regarded Maryland family, the Mancinis, who recently made a bizarre discovery involving their late patriarch and decades-old Sicilian mafia members. Their findings have revealed the existence of an unknown and mysterious sixth sibling. Meanwhile, and unrelated to the familial turmoil, a grandson and college student, Alex Mancini, has accepted a job as an intern with HSI while finishing his master’s degree. Part of his duties involves interviewing victims of human trafficking, recently rescued by HSI in a Tennessee investigation. While interacting with Agents on the investigation, Alex learns about Camelia’s mysterious disappearance in Mexico. Gripped by the story, he volunteers to determine Camelia’s current whereabouts. The probe places Alex, and by extension, his unsuspecting family, in the crosshairs of Mexican cartel members, who are poised to retaliate against US meddling in their criminal enterprise.
